Arrhenius equation
In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates. In 1889 while working with Wilhelm Ostwald at Leipzig University, Svante Arrhenius proposed the equation on the basis of the work of Dutch chemist Jacobus Henricus van 't Hoff, who had noted in 1884 that the Van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and reverse reactions.
