law of mass ac·tion
the rate of a chemical reaction is proportional to the concentrations of the reacting substances; when the forward reaction rate equals the reverse reaction rate (that is, at equilibrium) then, at constant temperature, the product of the concentrations of all the products divided by the product of the concentrations of all the reactants is itself a constant (Keq).
