Equilibria
Le Chatelier's Principle
Concentration
Increasing the concentration of a product causes the equilibrium to shift towards the reactants to remove the product.
Increasing the concentration of a reactant, the equilibrium shifts towards the products, to remove the reactants.
Pressure
Increasing the pressure shifts the equilibrium towards the side with fewer gas molecules, to reduce the pressure.
Decreasing the pressure shifts the equilibrium to the side with more gas molecules to raise the pressure
Temperature
-
Decreasing the temperature will shift the equilibrium in the exothermic direction to produce more heat.
The Equilibrium Constant

Factors affecting Kc
Temperature
Changing the temperature will change the Kc. For an exothermic reaction, increasing the temperature reduces the value of Kc. For an endothermic reaction, increasing the temperature increases the value of Kc.
