Abstract

Understanding the concept of ‘chemical equilibrium’ requires chemistry students to review the ideas they have previously developed around chemical reactions. In addition, teachers must try to ensure that students do not generate some related conceptual errors that are very persistent and thus act as barriers to learning. A historical study of the construction process of the key ideas that made up this concept can help in the design of laboratory activities for their teaching. This task is exemplified by several proposed experimental works where the following ideas are introduced: ‘incomplete reaction’ and ‘reversibility’. Finally, a simulation is presented to help students in the molecular dynamic explanation of these reactions.
