A reversible reaction is one in which the products of a reaction can react back to produce the original reactants.

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.

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.


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.

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.

An ICE I nitial, C hange, E quilibrium table is simple matrix formalism that used to simplify the calculations in reversible equilibrium reactions e. ICE tables are composed of the concentrations of molecules in solution in different stages of a reaction, and are usually used to calculate the K, or equilibrium constant expression, of a reaction in some instances, K may be given, and one or more of the concentrations in the table will be the unknown to be solved for. ICE tables automatically set up and organize the variables and constants needed when calculating the unknown. The procedure for filling out an ICE table is best illustrated through example. A sample consisting of 0.

Глаза Хейла расширились. Слова Сьюзан словно парализовали его, но через минуту он возобновил попытки высвободиться. - Он убьет. Я чувствую. Ведь я слишком много знаю. - Успокойся, Грег.

Но осуществить это намерение ей не пришлось. Внезапно кто-то начал колотить кулаком по стеклянной стене. Оба они - Хейл и Сьюзан - даже подпрыгнули от неожиданности. Это был Чатрукьян. Он снова постучал.

 Да будет.  - Хейл вроде бы затрубил отбой.  - Теперь это не имеет значения. У вас есть ТРАНСТЕКСТ. У вас есть возможность мгновенно получать информацию. Вы можете читать все, что пожелаете, - без всяких вопросов и запросов. Вы выиграли.

Chemical equilibrium

ТРАНСТЕКСТ не может с ним справиться. Сьюзан подумала о Стратморе, о том, как мужественно он переносит тяжесть этого испытания, делая все необходимое, сохраняя спокойствие во время крушения. Иногда она видела в нем что-то от Дэвида.

Халохот быстро осмотрел стодвадцатиметровую башню и сразу же решил, что прятаться здесь просто смешно. Наверняка Беккер не настолько глуп. Единственная спиральная лестница упиралась в каменную камеру квадратной формы, в стенах были проделаны узкие прорези для обозрения, но, разумеется, никакого выхода он не .
