Exploring energy and equilibrium through simple experiments Authors Klemens Koch Didactics of chemistry, Pedagogical University Berne and Gymnasium BielSeeland DOI: 10.2436/20.2003.02.251 Keywords: experiments, energy, heat and work, collision theory, catalysis, chemical equilibrium Abstract Energy moves us and entropy determines the direction, e.g. of chemical equilibria. They are behind chemistry, they accompany us through chemistry lessons and many everyday problems, such as the climate debate. This article aims to get to the bottom of the energy concepts in chemistry and their application in chemistry teaching by looking at about a dozen phenomena in ten experiments. The role of entropy is only touched on in passing; dealing with it explicitly would be a topic in itself.
