Zusammenfassung:Methods for demonstrating the concept of the activation energy have been reported (1, 2). These show the exothermic reaction only, and the equipment used is not available readily in many chemistry laboratories (2). This paper describes a modified method that can be used to present both the exothermic and endothermic cases. The apparatus is simple and easy to handle. The concept of the activation energy is clearly illustrated.
