 Law of mass action

The law of mass action assigns an elementary reaction a rate constant times the product of its reactant concentrations, with each concentration raised to its stoichiometric multiplicity.

The Law of Mass Action is a principle in chemistry that describes the relationship between the concentrations of reactants and products in a chemical reaction at equilibrium. It states that the rate of a chemical reaction is proportional to the product of the concentrations of the reactants, each raised to the power of their respective stoichiometric coefficients in the balanced chemical equation.
