Le Chatelier’s Principle
Le Chatelier’s principle states that:
The position of the equilibrium of a system changes to minimise the effect of any imposed change in conditions.
This means:
- Increasing the temperature favours the endothermic reaction
- Increasing the pressure in a gaseous reaction favours the side of the reaction which has the fewest number of gaseous molecules, because this will reduce the pressure.
- However adding a catalyst does not affect the position of the equilibrium.
