Factors Affecting Equilibria - Concentration
Chemistry: Cambridge International GCSE Supplement, topic 6.3.7
Concentration and the Position of Equilibrium
Changing the concentration of any reactant or product takes the system out of equilibrium. The system will react to try to restore the equilibrium.

Increase the concentration of a reactant
- This will shift the position of equilibrium towards the products.

Increase the concentration of a product
- This will shift the position of the equilibrium towards the reactants.
