Expert Answer:

The law of mass action is defined as at constant temperature , the rate of a forward reaction is directly proportional to the product of the molar concentration of the reactants each raised to a power equal to its stoichiometric coefficient that appear in the balanced chemical equation.
 
For example , consider the following general reaction;
                         aA + bB → Products

Hence, according to the law, rate of reaction = k [A]a [B]b, where 'a' and 'b' represents the stoichiometric coefficient of reactants A and B respectively and k is the rate constant.
