In this topic we explore what happens if we change the concentration of a reactant or product in a system at equilibrium.
After working through this topic you will be able to:
- use the Equilibrium Law to predict the effect on equilibrium composition of changing the concentration or pressure of a component of an equilibrium mixture and adding an inert gas;
- understand that Le Chatelier's Principle is a useful tool to aid in predicting the effect of changes to an equilibrium mixture but that it has its limitations;
- reflect on the teaching sequence that builds up skills and concepts students need to understand the effect of changing concentrations on an equilibrium;
- understand the misconceptions that students have about Le Chatelier's Principle and use strategies to help students develop their ideas.
