Law of mass action
In chemistry, Law of Mass Action has two aspects: 1) the equilibrium aspect, concerning the composition of a reaction mixture at equilibrium and 2) the kinetic aspect concerning the rate equations for elementary reactions. Both aspects stem from the research by Guldberg and Waage (1864-1879) in which equilibrium constants were derived by using kinetic data and the rate equation which they had proposed. Guldberg and Waage also recognised that chemical equilibrium is a dynamic process in which rates of reaction for the forward and backward reactions must be equal.
