Topics: Temperature, LeChatelier Predictions, and Equilibrium Definition
This activity uses color-changing reactions to explore chemical equilibrium, including the nature of reversible reactions and the use of LeChatlier’s principle. Students investigate the concentration of reactants and products, connecting these to the balance of forward and reverse reaction rates at equilibrium.
