Investigate the effects of concentration, pressure and temperature on equilibrium and explore Le Chatelier’s principle in this series of demonstrations

Le Chatelier’s principle describes how, when a dynamic equilibrium is disrupted by a change of pressure, temperature, volume or concentration, the position of equilibrium will shift to counteract any change and restore an equilibrium state.

In this series of teacher demonstrations, students can observe examples of Le Chatelier’s principle in action. The experiments use a variety of reactions and apparatus in order to illustrate the effects of changing different conditions, including concentration, temperature and pressure.

Each experiment includes a full kit list, safety instructions and teaching notes.
