law of chemical equilibrium & equilibrium constant

Consider a reversible reaction expressed by the following general equation: where A and B are two substances which react to form new substances C and D and C and D react under the same conditions forming the original substances A and B. Let us assume that the concentrations of these four substances..

The above equation is the law of chemical equilibrium. This law states: 'For a reversible reaction at equilibrium, the ratio of the product of the concentrations of the products to the product of the concentrations of the reactants each raised to a ..

When a chemical reaction gets started the reactants are present in the initial stage, but as the reaction proceeds, the concentration of the reactants decreases and that of products increases. Finally, a stage is reached when no further change in concentration of reactants and produ..

Heat Changes During Chemical Equilibrium - There are many reactions in which energy is evolved while in others energy is absorbed. Depending upon evolution or absorption of energy, the chemical reactions can be classified into two types: Exothermic reactions and endoth..

The chemical equilibrium has the following characteristics: Chemical equilibrium is dynamic in nature. The constancy of observable property in an equilibrium system does not mean that the reaction has stopped altogether. After the attainment of ..

The equilibrium can be attained only if the system is closed. A catalyst does not alter the equilibrium point. The equilibrium can be approached from either direction. The observable properties such as concentration, density of colour of the system become co..

Equilibrium Involving Chemical Systems - In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction an..

In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction and may be expressed as: In this reaction, the products cannot ..
