What is Le Chateliers Principle

Its the idea that if you change the conditions of a reversible reaction at equilibrium, the system will try to counteract that change

1 of 7

Effect of temperature decrease

If you decrease the temperature, the equilibrium will move in the exothermic direction to produce more heat. This means you will get more products for the exothermic reaction and fewer products for the endothermic reaction.

2 of 7

Effect of temperature increase

If you increase the temperature, the equilibrium will move in the endothermic direction to try and decrease it. You will get more products for the endothermic reaction and fewer products for the exothermic reaction

3 of 7

Effect of increase of pressure (only effects equilibrium involving gases)

If you increase the pressure, the equilibrium tries to reduce it- it moves in the direction where there are fewer molecules of heat

4 of 7

Effect of decrease of pressure

If you decrease pressure, the equilibrium tries to increase it- it moves in the direction where there are more molecules of gas

5 of 7

Effect of concentration increase

If you increase the concentration of the reactants the system tries to decrease it by making more products

6 of 7

Effect of concentration decrease

If you decrease concentration of products the system tries to increase it again by reducing the amount of reactants
