Abstract

The empirical rule (doubling of the reaction rate upon every 10° increase in temperature) is discussed on the basis of the Arrhenius equation and experimental data. A graph is plotted that shows the applicability limits of the empirical rule in terms of activation energies and temperatures. The historical origin of the rule mentioned is briefly discussed.
