Full Answer

The equilibrium equation for a chemical reaction is expressed in terms of the concentration of the reactants and products. Dynamic equilibrium occurs when the chemical reaction proceeds, but the amount of products and reactants remain constant. Chemical reactions behave similarly. They occur in both forward and backward directions, and when the both reaction rates become equal, products and reactants remain constant. This state is referred to as equilibrium.
