Cato Maximilian Guldberg

Born 11 Aug 1836; died 14 Jan 1902 at age 65.Norwegian chemist who, with his brother-in-law Peter Waage, formulated the law of mass action (1864), which details the effects of concentration, mass, and temperature on chemical reaction rates. The law states that the rate of a chemical change depends on the concentrations of the reactants. Thus for a reaction: A + B -> C the rate of reaction is proportional to [A][B], where [A] and [B] are concentrations. In 1870 Guldberg investigated the way in which the freezing point and vapor pressure of a pure liquid are lowered by a dissolved component. In 1890 he formulated Guldberg's law which relates boiling point and critical temperature.
