Abstract: The concept of chemical reaction is fundamental in the study of chemistry. This paper is based on a study which examines the nature and progression of sixth formers' understanding of the concept of chemical reactions. The main findings are that whilst most students gave a good account of the reactants and products involved, they were less able in their explanations of the processes and energetics of chemical reactions. Contrary to expectations for A-level, few students were able to utilise the scientists' approach of using a single consistent conceptual model to explain a multiplicity of superficially different events. Rather, these students held a variety of task-related alternative frameworks.
