Conditions and Equilibrium
Chemistry: Edexcel IGCSE, topic 14.3.3
Conditions and Equilibrium
Changing the conditions in a reversible reaction affects the position of equilibrium.

Changing conditions
- The relative amounts of the substances in a reaction at equilibrium are determined by the conditions.

Le Chatelier's principle
- Le Chatelier’s principle says that if any of the conditions of a reversible reaction at equilibrium are changed, the closed system will adapt to counteract whatever has changed.
- This principle is used to predict the outcome of changes imposed on a system at equilibrium.
