قانون فاعلية الكتلة: الفرق بين النسختين

 

In Chemistry, the law of mass action is a mathematical model that explains and predicts behaviors of [[solutions]] in [[dynamic equilibrium]]. It can be described with two aspects: 1) the equilibrium aspect, concerning the composition of a [[chemical reaction|reaction]] mixture at [[chemical equilibrium|equilibrium]] and 2) the [[chemical kinetics|kinetic]] aspect concerning the [[rate equation]]s for [[elementary reaction]]s. 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 recognized that chemical equilibrium is a dynamic process in which [[reaction rate|rates of reaction]] for the forward and backward reactions must be equal.
