Episode 6 — Chemical Equilibrium

and le Chateliers Principle

Learners will be able to:

• Describe the characteristics of reversible chemical reactions and represent them graphically. • Identify dynamic equilibrium as a state in which the forward and reverse reactions occur at the same rate in a closed system. • Explain Le Chatelier's principle and its application to predict changes in equilibrium position due to external influences. • Calculate the effect of concentration on the position of equilibrium for a given reversible reaction. • Describe how pressure affects the position of equilibrium, including situations where it has no effect. • Apply Le Chatelier's principle to explain how temperature affects the position of equilibrium.
