Democracy has in the 20th and 21st century grown in popularity, which has been credited due to the ‘waves of democracy’, which has been caused by a variety of reasons all over the world. However because of the growth of democracy, it has led to debate between academics as to whether or not presidentialism has had a positive or negative effect on new and developing democracies. In this essay it will discuss the effect presidentialism has had on democracy as a system of government. A brief background of democracy will be spoken about, especially what affect the ‘waves of democracy’ has had on new democratic systems. Moreover the affect that institutional design plays in maintaining a stable political system, in terms of representation†¦show more content†¦With this wave of democracy came the redesign of political institution. The institutional design of a presidentialism and parliamentary system is also hugely important during the development of new democracies. The process of designing institutions is the first step is providing a platform for those who are involved in policy making. It can also led to creating incentivise and As mentioned previously Linz is a noted political and social scientist, who main areas of expertise is in creating a greater understanding of how democracy, totalitarianism and authoritarianism systems operate. Linz view on presidentialism was that this type of political system was less likely than a parliamentary system to be able to maintain a stable democratic system. This was because in presidential systems, the executive has considerably more constitutional powers, than the executive in a parliamentary system. Linz had this beliefs as he believed a president held too much power, as a president was not only the executive power holder, but was also perceived as the symbolic head of state (Linz, 1990). Further evidence of presidential power described by Linz in a presidentialism system, was the control they possessed over the composition of their cabinet and their administration. Furthermore even though a president is elected by the voters, presidents do not require a vote of confidence by the states parliament as they are independent. This was a major concern in the view

She was in his mind. It was all around her, like astrange and perilous world. A terribly frighteningworld, but one that was full of stark beauty. We will write a custom essay sample on Night World : Black Dawn Chapter 9 or any similar topic only for you Order Now Everything was angles, as if she’d fallen into theheart of a giant crystal. Everything glittered, coldand clear and sharp. There were flashes of color aslight shimmered and reflected, but for the most part it was dazzling transparency in every direction. Like the fractured ice of a glacier. Really dangerous,Maggie thought. The spikes of crystal around her had edges like swords. The place looked as if it had never known warmth or softcolor. And youlive here?she thought to Delos. Go away.Delos’s answering thought came to her.on a wave of cold wind. Get out! No,Maggie said. You can’t scare me. I’ve climbed glaciers before.It was then that she realized whatthis place reminded her of. A summit. The bareand icy top of a mountain where no plants-andcertainly no people-could survive. But didn’tanything goodever happen to you? shewondered. Didn’t you ever have a friend†¦or apet†¦ or something? No friends,he said shortly. No pets. Get out of here before I hurt you. Maggie didn’t answer, because even as he said itthings were changing around her. It was as if the glinting surfaces of the nearby crystals were suddenly reflecting scenes, perfect little pictures withpeople moving in them. As soon as Maggie lookedat one, it swelled up and seemed to surround her. They were his memories. She was seeing bits ofhis childhood. She saw a child who had been treated as aweapon from the time he was born. It was all aboutsome prophecy. She saw men and women gatheredaround a little boy, four years old, whose blacklashed golden eyes were wide and frightened. â€Å"No question about it,† the oldest man was saying. Delos’s teacher, Maggie realized, the knowledge flowing to her because Delos knew it, and shewas in Delos’s mind. â€Å"This child is one of the Wild Powers,† theteacher said, and his voice was full of awe andfear. His trembling hands smoothed out a brittlepiece of scroll. As soon asMaggie saw it she knew that the scroll was terribly old and had been keptin the Dark Kingdom for centuries, preserved hereeven when it was lost to the outside world. â€Å"Four Wild Powers,† the old man said, â€Å"who willbe needed at the millennium to save the world-or-to destroy it. The prophecy tells where they willcome from.† And he read: â€Å"One from the land of kings long forgotten; One from the hearth which still holds the spark; One from the Day World where two eyes are watching; One from the twilight to be one with the dark.†, The child Delos looked around the circle of grim faces, hearing the words but not understandingthem. â€Å"‘The land of kings, long forgotten,†Ã¢â‚¬Ëœ a womanwas saying. â€Å"That must be the Dark Kingdom.† â€Å"Besides, we’ve seen what he can do,† a big mansaid roughly. â€Å"He’s a Wild Power, all right. The bluefire is in his blood. He’s learned to use it too early, though; he can’t control it. See?† He grabbed a small arm-the left one-and heldit up. It was twisted somehow, the fingers clawed and stiff, immobile. The little boy tried to pull his hand away, but hewas too weak. The adults ignored him. â€Å"The king wants us to find spells to hold thepower in,† the woman said. â€Å"Or he’ll damage himself permanently.† â€Å"Not to mention damaging us,† the rough mansaid, and laughed harshly. The little boy sat stiff and motionless as theyhandled him like a doll. His golden eyes were dryand his small jaw was clenched with the effort notto give in to tears. That’s awful,Maggie said indignantly, aiming herthought at the Delos of the present. It’s a terrible way to grow up. Wasn’t there anybody who cared about you? Your father? Goaway, he said. I don’t need your sympathy. And your arm,Maggie said, ignoring the cold emptiness of his thought. Is that what happens toitwhen you use the blue fire? He didn’t answer, not in a thought directed ather. But another memory flashed in the facets of a crystal, and Maggie found herself drawn into it. She saw a five-year-old Delos with his armwrapped in what looked like splints or a brace. Asshe looked at it, she knew it wasn’t just a brace. It was made of spells and wards to confine the blue fire. â€Å"This is it,† the woman who had spoken beforewas saying to the circle of men. â€Å"We can controlhim completely.† â€Å"Are you sure? You witches are careless sometimes. You’re sure he can’t use it at all now?† Theman who said it was tall, with a chilly, austereface-and yellow eyes like Delos’s. Your father,Maggie said wonderingly to Delos. And his name was †¦ Tormentil? But †¦She couldn’t go on, but she was thinking that he didn’tlook much like a loving father. He seemed just likethe others. â€Å"Until I remove the wards, he can’t use it at all.I’m sure, majesty.† The woman said the last word in an everyday tone, but Maggie felt a little shock.Hearing somebody get called majesty-it made him moreof a king, somehow. â€Å"The longer they’re left on, the weaker he’ll be,† the woman continued. â€Å"And hecan’t take them offhimself. But I can, at any time – â€Å" â€Å"And then he’ll still be useful as a weapon?† â€Å"Yes. But blood has to run before he can use the blue fire.† The king said brusquely, â€Å"Show me.† The woman murmured a few words and strippedthe brace off the boy’s arm. She took a knife fromher belt and with a quick, casual motion, like Maggie’s grandmother guttinga salmon, opened a gash on his wrist. Five-year-old Delos didn’t flinch or make asound. His golden eyes were fixed on his father’s faceas blood dripped onto the floor. â€Å"I don’t think this is a good idea,† the old teachersaid. â€Å"The blue fire isn’t meant to be used like this,and it damages his arm every time he does it= â€Å"Now,† the king interrupted, ignoring him andspeaking to the child for the first time. â€Å"Show mehow strong you are, son. Turn the blue fire on †¦Ã¢â‚¬  He glanced up deliberately at the teacher. â€Å"Let’ssay-him.† â€Å"Majesty!† The old man gasped, backing againstthe wall. The golden eyes were wide and afraid. â€Å"Do it!† the king said sharply, and when the littleboy shook his head mutely, he closed his hand onone small shoulder. Maggie could see his fingerstighten painfully. â€Å"Do what I tell you. Now!† Delos turned his wide golden eyes on the old man, who was now shrinking and babbling, his trembling hands held up as if to ward off a blow. The king changed his grip, lifted the boy’s arm. â€Å"Now, brat! Now!† Blue fire erupted. It poured in a continuousstream like the water from a high-power fire hose.It struck the old man and spreadeagled him againstthe wall, his eyes and mouth open with horror. Andthen there was no old man. There was only a shad owy silhouette made of ashes. â€Å"Interesting,† the king said, dropping the boy’sarm. His anger had disappeared as quicklyasithad come. â€Å"Actually, I thought there would bemore power. I thought it might take out the wall.† â€Å"Give him time.† The woman’s voice was slightlythick, and she was swallowing over and over. â€Å"Well, no matter what, hell be useful.† The kingturned to look at the others in the room. â€Å"Remember-all of you. A time of darkness is coming. Theend of the millennium means the end of the world.But whatever happens outside, this kingdom isgoing to survive.† Throughout all of this, the little boy sat andstared at the place where the old man had been.His eyes were wide, the pupils huge and fixed. Hisface was white, but without expression. Maggie struggled to breathe. That’s-that’s themost terrible thing I’ve ever seen.She could hardly get the words of her thought out. Theymade you kill your teacher-he made you do it. Yourfather. She didn’t know what to say. Sheturned blindly, trying to find Delos himself in this strange landscape, trying to talk to him directly.She wanted to look at him, to hold him. To comfort him. I’m so sorry. I’mso sorry you had to grow uplike that. Don’t be stupid,he said. I grew up to be strong.That’s what counts. You grew up without anyone loving you,Maggiesaid. He sent a thought like ice. Love is for weak people. It’s a delusion. And it can be deadly. Maggie didn’t know how to answer. She wanted to shake him. All that stuff about the end of the millennium and the end of the world-what did that mean? Exactly what it sounded like,Delos said briefly. The prophecies are coming true. The world o f hu mans is about to end in blood and darkness. And then the Night People are going to rule again. And that’s why they turned a five-year-old into alethal weapon? Maggie wondered. The thoughtwasn’t for Delos, but she could feel that he heard it. I am what I was meant to be,he said. And I don’t want to be anything else. Are you sure?Maggie looked around. Althoughshe couldn’t have described what she was doing, she knew what it was. She was looking forsomething†¦ something to prove to him †¦ A scene flashed in the crystal. The boy Delos was eight. He stood in front of apile of boulders, rocks the size of small cars. Hisfather stood behind him. â€Å"Now!† As soonasthe king spoke, the boy lifted his arm.Blue fire flashed. A boulder exploded, disintegrating into atoms. Again! Another rock shattered. â€Å"More power! You’re not trying. You’re useless!†The entire pile of boulders exploded. The bluefire kept streaming, taking out a stand of trees behind the boulders and crashing into the side of amountain. It chewed through the rock, meltingshale and granite like a flamethrower burning awooden door. The king smiled cruelly and slapped his son onthe back. â€Å"That’s better.† No. That’s horrible,Maggie told Delos. That’swrong. This is what it should be like. And she sent to him images of her own family.Not that the Neelys were anything special. Theywere like anybody. They had fights, some of them pretty bad. But there were lots of good times, too, and that was what she showed him. She showed him her life†¦ herself. Laughingasher father frantically blew on a flaming marshmallow on some long-past campingtrip. Smelling turpentine and watching magical colors unfold on canvasas her mother painted. Perch ing dangerously on the handlebars of a bike while Miles pedaled behind her, then shrieking all theway down a hill. Waking up to a rough warmtongue licking her face, opening one eye to see Jake the Great Dane panting happily. Blowing out candles at a birthday party. Ambushing Miles from herdoorway with a heavy-duty water rifle †¦ Who is that?Delos asked. He had been thawing;Maggie could feel it. There were so many thingsin the memories that were strange to him: yellowsunshine, modern houses, bicycles, machinerybut she could feel interest and wonder stir in himat the people. Until now, when she was showing him a sixteenyear-old Miles, a Miles who looked pretty muchlike the Miles of today. That’s Miles. He’s my brother. He’s eighteen and he just started college.Maggie paused, trying to feel what Delos was thinking. He’s the reason I’m here.He got involved with this girl called Sylvia-Ithinkshe’s a witch. And then he disappeared. I went tosee Sylvia, and the next thing I know I’m waking up ina slave-trader’s cart. In a place I never knew existed. Delos said, I see. Delos, do you know him? Have you seen him be fore?Maggie tried to keep the question calm. She would have thought she could see anything thatDelos was thinking, that it would all be reflected inthe crystals around her, that there was nothing he could hide. But now suddenly she wasn’t sure. It’s best for you to leave that alone,Delos said. I can’t,Maggie snapped back. He’s my brother! If he’s in trouble I have to find him-I have to helphim. That’s what I’ve been trying to explainto you. We help each other. Delos said, Why? Because we do. Because that’s what people are supposed to do. And even you know that, somewhere down deep. You were trying to help me in my dream She could feel him pull away. Your dreams are just your fantasies. Maggie said flatly, No. Not this one. I had it before I met you. She could remember more of it now. Here in his mind thedetailswere coming to her, all the things that had been unclear before. And there was onlyone thing to do. She showed it to Delos. The mist, the figure appearing, calling her name.The wonder and joy in his face when he caughtsight of her. The way his hands closed on hershoulders, so gently, and the look of inexpressibletenderness in his eyes. And then -I remember!Maggie said. Youtold meto look for a pass,underneath a rock thatlooked likea wave about to break You told me to get awayfromhere, to escape. Andthen†¦ She remembered what had happened then, andfaltered. And then he had kissed her. She could feel it again, his breath a soft warmthon her cheek, and then the touch of his lips, just as soft. There had been so much in that kiss, somuch of himself revealed. It had been almost shy in its gentleness, but charged with a terrible passion, as if he had known it was the last kiss theywould ever share. It was †¦ so sad,Maggie said, faltering again.Not from embarrassment, but because she was suddenly filled with an intensity of emotion that fright ened her. I don’t know what it meant, but it was so sad†¦. Then, belatedly, she realized what was happeningwith Delos. He was agitated. Violently agitated. The crystalworld around Maggie was trembling with denialand fury-and fear. That wasn’t me. I’m not like that,he said in avoice that was like a sword made of ice. It was,she said, not harshly but quietly. I don’t understand it, but it really was you. I don’t understand any of this. But there’s a connection betweenus. Look what’s happening to us right now. Is thisnormal? Do you people always fall into each oth ers’ minds? Get out!The words were a shout that echoedaround Maggie from every surface. She could feel his anger; it was huge, violent, like a primal storm. And she could feel the terror that was underneath it, and hear the word that he was thinking anddidn’t want to think, that he was trying to bury and run away from. Soulmates.That was the word. Maggie couldsense what it meant. Two people connected, boundto each other forever, soul to soul, in a way thateven death couldn’t break. Two souls that were destined for each other. It’s a lie,Delos said fiercely. I don’t believe in souls. I don’t love anyone. And I don’t have any feelings! And then the world broke apart. That was what it felt like. Suddenly, all aroundMaggie, the crystals were shattering and fracturing.Pieces were falling with the musical sound of ice.Nothing was stable, everything was turning to chaos. And then, so abruptly that she lost her breath,she was out of his mind. She was sitting on the ground in a small cave lit only by a dancing, flickering flame. Shadows wavered on the walls and ceiling. She was in her ownbody, and Delos was holding her in his arms. But even as she realized it, he pulled away and stood up. Even in the dimness she could see that his face was pale, his eyes fixed. As she got to her feet, she could see somethingelse, too. It was strange, but their minds were still connected, even though he’d thrown her out of his world. And what she saw†¦was herself. Herselfthrough his eyes. She saw someone who wasn’t at all the frailblond princess type, not a bit languid and perfect and artificial. She saw a sturdy, rosy-brown girlwith a straight gaze. A girl with autumn-coloredhair, warm and vivid and real, and sorrel-coloredeyes. It was the eyes that caught her attention: there was a clarity and honesty in them, a depth and spaciousness that made mere prettiness seem cheap. Maggie caught her breath. Do I look like that? she wondered dizzily. I can’t. I’d have noticed inthe mirror. But it was how he saw her. In his eyes, she wasthe only vibrant, living thing in a cold world of black and white. And she could feel the connectionbetween them tightening, drawing him toward her even as he tried to pull farther away. â€Å"No.†His voice was a bare whisper in the cave.†I’m not bound to you. I don’t love you.† â€Å"Delos-!’ I don’t love anyone. I don’t have feelings.† Maggie shook her head wordlessly. She didn’thave to speak, anyway. All the time he was tellingher how much he didn’t love her, he was moving closer to her, fighting it every inch. â€Å"You mean nothing to me,† he raged through clenched teeth. â€Å"Nothing!† And then his face was inches away from hers, and she could see the flame burning in his golden eyes. â€Å"Nothing,† he whispered, and then his lipstouched hers.

To what extent was the United States responsible for the collapse of the Grand Alliance at the end of the Second World War Essay Example

To what extent was the United States responsible for the collapse of the Grand Alliance at the end of the Second World War Essay Example To what extent was the United States responsible for the collapse of the Grand Alliance at the end of the Second World War Paper To what extent was the United States responsible for the collapse of the Grand Alliance at the end of the Second World War Paper to complete the formation of a bloc of several European countries hostile to the interests of the democratic countries of Eastern Europe and most particularly to the interests of the Soviet Union. 8 (italics original). Some historians since have been sympathetic to this view; W. A. Williams argues that the postwar atmosphere degenerated into hostility in large part because of American insistence on an open-door policy of total free trade between nations, rather than, offer[ing] the Soviet Union a settlement based on other, less grandiose, terms. 9 However, this argument is predicated on the assumption that eastern Europe was already in economic isolation from the west, whereas in fact this was a state of affairs forcibly created by the USSR. Therefore, if the Marshall Plan did increase postwar tensions this was only because of the actions already taken by the Soviet Union; without communist domination of east Europe, a plan to revive shattered economies in former warzones would not have had the degenerative effect on international relations which it evidently did have. In this sense, the Marshall Plan was a response to the Soviet aggression which had caused Cold War tensions to increase, rather than an ipso facto cause of antipathy itself. There are other examples given of where the west was responsible for an increase in superpower hostility following 1945 however. One episode deserves special mention: US interference in the Italian general election of 1948. American and British officials were concerned that in the war-ravaged countries of France and Italy, economic hardship might result in communist parties coming to power through free elections; by 1946 such organisations already seemed poised to become the largest single political forces within those countries. 0 These worries quickly disappeared in the case of France, but when an election was scheduled for April 18th 1948 in Italy, the Italian communist party, at two million members the largest outside of the Soviet bloc, was poised certainly to win a large enough share of the vote to make it impossible to keep them out of a governing coalition, and possibly an outright majority. The United States decided to intervene. A massive letter-writing campaign was organised, resulting in some ten million letters being sent by Italian-Americans to relatives in Italy arguing against a vote for the communists, and the CIA in conjunction with the Catholic Church ran a huge anti-Marxist propaganda campaign. In addition, some $2-3 million was distributed by the CIA to various anti-communist political parties in Italy. When election day came the communists were humiliated, their share of the vote halved from what they had achieved in the 1946 local elections. 1 This is not the place to discuss whether American actions were justified, but undoubtedly the precedent set by the Italian effort, and its resounding success, resulted afterwards in the United States being far more willing to engage in anti-Soviet activities elsewhere, and this case is therefore cited as an instance where the actions of America contributed to the breakup of the Grand Alliance. Another reason sometimes given is the American monopoly on nucl ear weapons in the aftermath of World War Two. On July 16th 1945, the largest man-made explosion in history took place at the Alamogordo test site in New Mexico,12 and the United States was immediately catapulted into a position of total military superiority. Though the Soviet Union had ended the war with colossal conventional armed forces, the atomic bombings of Japan in August of that year left the Russians in no doubt that their on-paper ally had become indisputably the most powerful military force in the history of the world. It has therefore been argued that this obvious fact caused Stalin and his government to feel threatened and bullied by the United States, and that this was the reason for the antagonistic nature of postwar negotiations. Williams again writes: Particularly after the atom bomb was created and used, the attitude of the United States left the Soviets with but one real option: either acquiesce in American proposals or be confronted with American power and hostility. 13 Undoubtedly the US was sometimes guilty of flaunting its nuclear dominance: American officials evidently thought that the Paris Peace Conference of July 1946 would be far more productive were it to be immediately preceded by two nuclear weapons tests. 14 On the other hand, it is quite possible that considerations of American nuclear power did not factor significantly into Soviet thinking. At the Potsdam conference (July-August 1945), more than one western official observed Stalins surprising calmness, even nonchalance, when told by President Truman that the US was in possession of a new weapon of unusual destructive force. Only later did it transpire that not only did the USSR have an atomic weapons programme dating back to 1942 but that, due to the laxness of the Manhattan Projects managers respecting its wartime ally,15 the Soviets had spies passing nuclear secrets to Moscows scientists. 6 Stalin was therefore fully aware that the United States monopoly on atomic weapons would be only temporary, and therefore that this need not be factored into long-term Soviet strategic thinking. Furthermore, the aggressive actions taken by the USSR in the postwar period (see below) show no signs of restraint by Russian leaders on account of the destructive capability of the Americans nuclear arsenal. The Berlin Blockade (June 1948-May 1949) took place and concluded before the Soviets successfully tested a nuclear bomb of their own on August 29th 1949. 7 The USSRs leaders seem to have calculated, probably correctly, that the United States wanted to avoid war with the Soviet Union at almost any cost; after August 1949 this only became more true as MAD thinking began to gain widespread acceptance. The more orthodox interpretation of the postwar period is that the alliance collapsed primarily because of the actions taken by the Soviet Union after the defeat of Germany, especially concerning the areas of Europe occupied by soldiers of the Red Army. At the Yalta conference in February 1945, only months away from the defeat of Germany, major disputes arose over the fate of European nations such as Poland, Hungary and Czechoslovakia which had been liberated from German control by the troops of the Soviet Union. The western leaders, President Franklin D. Roosevelt and Prime Minister Winston Churchill, wanted Stalin to conduct free and fair elections with the aim of establishing self-governing sovereign entities, but were under no illusions that the Soviet leader intended to turn them into friendly buffer states, and probably totalitarian one-party regimes at that. With respect to Poland especially, Stalin had already shown his contempt for national democracy movements by allowing the Wehrmacht to crush the Warsaw uprising in August-October 1944, and had a pro-Soviet puppet government ready and waiting to take over from the German authorities. 18 Previous Soviet treatment of Finland and the Baltic states gave every indication needed of how Stalin would react to attempts made at installing democracy in other countries. Section V pledged all of the allied powers, including the Soviet Union, to the earliest possible establishment through free elections of Governments responsive to the will of the people, and asserted the right of all people to choose the form of government under which they will live. 19 It does not need to be repeated that Stalin never had any intentions of carrying out the requirements of this passage. Immediately after the war the leaders of national communist parties, many of whom had spent the pre-war and wartime years in exile in Moscow and had long been subdued under Stalins whip, began their gradual accumulation of power. Invariably, the communists would contest a free-ish election under the auspices of the Red Army, win a minority of the vote (as little as 17% in Hungary and never more than 38%, in Czechoslovakia), and then agree to take part in a coalition government. Under pressure from Stalin, their rivals would agree to give communists control of ministries of justice and of the interior, which would then be used to disappear political opponents. In Poland the Soviet puppets methods were less subtle: a massive campaign of violence and intimidation preceded the first postwar elections in 1947, and the communists claimed 80% of the vote. 20 Despite assertions by some historians that western leaders handed over Eastern Europe to the Soviets at Yalta, short of a full-scale war with the USSR there was little if anything Roosevelt and Churchill could have done to prevent Stalin from turning eastern European countries into satellite states. Nevertheless, the dictators flagrant violations of the USSRs promises at Yalta created a chasm between the former Allies even before V-E Day, and is therefore frequently cited as the primary reason for the collapse of the Grand Alliance. As Roosevelts biographer Conrad Black has written, The issue of whether the British and Americans (and Frances) foremost ally would be Germany or Russia would be determined by whether Stalin could resist the temptation of enslaving Eastern Europe. 21

What Is Dynamic Equilibrium Definition and Examples

What Is Dynamic Equilibrium Definition and Examples SAT / ACT Prep Online Guides and Tips Dynamic equilibrium is an important concept in chemistry. But what is dynamic equilibrium exactly? How can something be dynamic but also at equilibrium? Keep reading to learn the best dynamic equilibrium definition, common dynamic equilibrium examples, and how dynamic and static equilibrium may look the same but are in fact very different. What Is Dynamic Equilibrium? Chemical reactions can either go in both directions (forward and reverse) or only in one direction. The ones that go in two directions are known as reversible reactions, and you can identify them by the arrows going in two directions, like the example below. H2O(l) â‡Å' H+(aq) + OH-(aq) Dynamic equilibrium only occurs in reversible reactions, and it’s when the rate of the forward reaction is equal to the rate of the reverse reaction. These equations are dynamic because the forward and reverse reactions are still occurring, but the two rates are equal and unchanging, so they’re also at equilibrium. Dynamic equilibrium is an example of a system in a steady state. This means the variables in the equation are unchanging over time (since the rates of reaction are equal). If you look at a reaction in dynamic equilibrium, it’ll look like nothing is happening since the concentrations of each substance stay constant. However, reactions are actually continuously occurring. Dynamic equilibrium doesn't just occur in chemistry labs though; you've witnessed an dynamic equilibrium example every time you've had a soda. In a sealed bottle of soda, carbon dioxide is present in both the liquid/aqueous phase and the gaseous phase (bubbles). The two phases of carbon dioxide are in dynamic equilibrium inside the sealed soda bottle since the gaseous carbon dioxide is dissolving into the liquid form at the same rate that the liquid form of carbon dioxide is being converted back to its gaseous form. The equation looks like this: CO2(g) â‡Å' CO2(aq). Changing the temperature, pressure, or concentration of a reaction can shift the equilibrium of an equation and knock it out of dynamic equilibrium. This is why, if you open a soda can and leave it out for a long time, eventually it'll become "flat" and there will be no more bubbles. This is because the soda can is no longer a closed system and the carbon dioxide can interact with the atmosphere. This moves it out of dynamic equilibrium and releases the gaseous form of carbon dioxide until there are no more bubbles. Dynamic Equilibrium Examples Any reaction will be in dynamic equilibrium if it’s reversible and the rates of the forward and reverse reactions are equal. For example, say that you prepare a solution that is saturated with an aqueous solution of NaCl. If you then add solid crystals of NaCl, the NaCl will be simultaneously dissolving and recrystallizing within the solution. The reaction, NaCl(s) â‡Å' Na+(aq) + Cl-(aq), will be in dynamic equilibrium when the rate of the dissolution of the NaCl equals the rate of recrystallization. Another example of dynamic equilibrium isNO2(g) + CO(g) â‡Å' NO(g) + CO2(g) (again, as long as the two rates are equal). Nitrogen dioxide (NO2) reacts with carbon monoxide (CO) to form nitrogen oxide (NO) and carbon dioxide (CO2), and, in the reverse reaction, nitrogen oxide and carbon dioxide react to form nitrogen dioxide and carbon monoxide. If you’re observing a reaction, you can tell it’s not at dynamic equilibrium if you can see changes occurring in the amounts of reactants or products. (If you can’t see any changes, that doesn’t guarantee it’s at dynamic equilibrium, since it may be at static equilibrium or the changes may be too small to see with the naked eye.) An example of an equation that could never be at dynamic equilibrium is: 4 Fe(s) + 6 H2O(l) + 3O2(g) → 4 Fe(OH)3(s). This is an equation for the formation of rust. We can see that it’ll never be in dynamic equilibrium because the arrow for the reaction only goes one way (which is why a rusty car won’t become shiny again on its own). There's no dynamic equilibrium for this car! Dynamic Equilibrium vs Static Equilibrium If you observe reactions at dynamic equilibrium and reactions at static equilibrium, neither will have visible changes occurring, and it'll look like nothing is happening. However, reactions at static equilibrium are actually very different from those at dynamic equilibrium. Static equilibrium (also known as mechanical equilibrium) is when the reaction has stopped and there is no movement at all between the reactants and products. The reaction is complete and the forward and reverse reaction rates are both 0. While reactions at dynamic equilibrium are reversible (can proceed in either direction), those at static equilibrium are irreversible and can only proceed in one direction.However, both dynamic equilibrium and static equilibrium are examples of systems at steady state, in which the net force action on the systems is zero. Below is a chart showing the key differences between dynamic and static equilibrium. Dynamic Equilibrium Static Equilibrium Reversible Irreversible Reaction is still occurring Reaction has stopped Rate of forward reaction = rate of reverse reaction Both reaction rates are zero Occurs in a closed system Can occur in an open or closed system How Does Dynamic Equilibrium Relate to Rate Constants? When a reaction is at dynamic equilibrium, the reaction will have a specific rate constant, known as the equilibrium constant, or Keq. The equilibrium constant, or rate constant, is a coefficient that shows the reaction quotient (or the relative amounts of products and reactants in the reaction at a given point in time) when the reaction is at equilibrium. The value of the equilibrium constant will tell you the relative amounts of product and reactant at equilibrium. If Keqis 1000, at equilibrium there will be mostly product. If Keqis between .001 and 1000, at equilibrium there will be a significant amount of both product and reactant. If Keqis .001, at equilibrium there will be mostly reactant. For the reactionaA + bBâ‡Å'cC+dD, A and B represent the reactants and C and D represent the products. The equation for the equilibrium constant is Keq=[C]c[D]d/[A]a[B]b. Example Take the reaction N2(g)+O2(g)⇋2NO(g). Using the equation for the equilibrium constant, Keqis equal to [NO]2/[N2][O2]. You would either leave the equation like this, or, if you're given equilibrium concentrations/the equilibrium constant, you can plug those in to find any missing values. Say we know the concentrations of both[N2] and [O2]=.15 M and the concentration of [NO] is 1.1 M. Plugging in those values would give you: Keq= (1.1)2/(.15)(.15) or 1.21/.0225. You can solve and find that Keq=53.8. SinceKeqis between .001 and 1000, there will be a significant amount each of NO, O2, and N2at equilibrium. Summary: What Is Dynamic Equilibrium? What is the best dynamic equilibrium definition? Dynamic equilibrium occurs when, for a reversible reaction, the rate of the forward reaction equals the rate of the reverse reaction.Since the two rates are equal, it looks like nothing is happening, but in reality the reaction is continuously occurring at its stable rate. In contrast, reactions at stable equilibrium are complete and no further reaction is occurring. The equation for the equilibrium constant isKeq=[C]c[D]d/[A]a[B]b. What's Next?
