An Accelerated Storage Test with Programmed Temperature Rise

Abstract

Abstract The rate constant of a reaction at room temperature and the activation energy can be calculated from values of the concentration of the reactant as a function of time. Measurements are made while the temperature of the reacting system is raised in accordance with a predetermined programme. The method makes use of the Arrhenius equation, but it does not suffer from the disadvantages of the usual method in which several experiments are done at fixed elevated temperatures.
