- demonstrate on specified chemical reactions how Le Châtelier’s Principle is applied to equilibrium systems.
- describe the effect of concentration on an equilibrium system.
- demonstrate with specific equations how Le Châtelier’s Principle explains the effect of concentration.
- describe the effect of pressure as a stress on the equilibrium position.
- describe the pressure effect in Le Châtelier’s Principle.
- describe the effect of temperature as a stress on an equilibrium system.
- explain how Le Châtelier’s principle explains the effect of temperature.
- explain how a catalyst works in equilibrium reactions.
- explain the effect of a catalyst in equilibrium positions.
