Balanced Equations and Equilibrium Constants

Irreversible reactions Most chemical reactions are considered irreversible the products that are made cannot readily be changed back into their reactants. For example, when wood burns it is impossible to turn it back into unburnt wood again! Similarly, when magnesium reacts with hydrochloric acid to form magnesium chloride and hydrogen, it is not easy to reverse the reaction and obtain the magnesium. What are reversible reactions? Reversible reactions occur when the backwards reaction products reactants takes place relatively easily under certain conditions. The products turn back into the reactants.

A reversible reaction is one in which the products of a reaction can react back to produce the original reactants. The reaction can go both ways:. If the reaction is carried out in a closed container, a point is reached where the concentration of products and reactants does not change. We say that an equilibrium balance has been reached. The amounts of reactants and products present at equilibrium depend on the temperature, pressure and concentration of reactants at the start. If we remove the products from an equilibrium reaction more reactants are converted to products.

In a chemical reaction , chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactants and products. Such a state is known as dynamic equilibrium. The concept of chemical equilibrium was developed after Berthollet found that some chemical reactions are reversible. The equilibrium concentration position of a reaction is said to lie "far to the right" if, at equilibrium, nearly all the reactants are consumed.

Reversible reactions occur when the backwards reaction products reactants takes place relatively easily under certain conditions. The products turn back into the reactants.

For any reaction mixture to exist at equilibrium, the rates of the forward and backward (reverse) reactions are equal. In the following chemical equation with.

Полнейшее безумие. - Это невозможно! - воскликнула она.  - Вы проверили сигналы ошибки. Быть может, в ТРАНСТЕКСТЕ какой-нибудь сбой и… - Все в полном порядке. - Но это значит, что пароль неимоверной длины.

Японец, подумал Беккер. - Бедняга. Сердечный приступ. Беккер безучастно кивнул: - Так мне сказали. Лейтенант вздохнул и сочувственно помотал головой.

Затем взял бутылку оливкового масла и прямо из горлышка отпил несколько глотков. Он считал себя большим знатоком всего, что способствовало укреплению здоровья, и утверждал, что оливковое масло очищает кишечник. Он вечно навязывал что-то коллегам, например морковный сок, и убеждал их, что нет ничего важнее безукоризненного состояния кишечника. Хейл поставил масло на место и направился к своему компьютеру, располагавшемуся прямо напротив рабочего места Сьюзан. Даже за широким кольцом терминалов она почувствовала резкий запах одеколона и поморщилась.

Стратмор кивнул: - Совершенно.  - Повисла продолжительная пауза.  - Прости, что я тебе лгал. Попытка переделать Цифровую крепость - дело серьезное и хлопотное. Я не хотел тебя впутывать. - Я… понимаю, - тихо сказала она, все еще находясь под впечатлением его блистательного замысла.
