State and explain the law of mass action. Derive an expression for the equilibrium constantfor a reversible reaction.
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 , considerthe 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...
