The Determination of the Arrhenius Parameters Using Linear Programmed Temperature Elevation System

Abstract

A simple method for the determination of the activation energy and the frequency factor of the Arrhenius equation was developed, An equation which correlates the reaction time with temperature in an ordinary linear programmed temperature experiment was derived and was successfully applied to evaluate the Arrhenius expression of the rate constants of several reactions.
In this method, the Arrhenius expression can be determined by only a single run of rate measurment instead of the multiple runs as a function of temperature. The decomposition of hydrogen peroxide and the saponification of ethyl acetate were analyzed by this method; thus obtained rate parameters were shown to agree with those from conventional methods.
