Factors affecting Equilibrium

Factor	Increase of Factor	Decrease of Factor
Temperature	Equilibrium shifts to decrease the temperature so it shifts to the endothermic direction	Equilibrium shifts to increase the temperature so it shifts to the exothermic direction
Concentration	Equilibrium shifts to decrease the concentration	Equilibrium shifts to increase the concentration
Pressure	Equilibrium shifts to decrease the pressure so it shifts in the direction of the least molecules	Equilibrium shifts to increase the pressure so it shifts in the direction of the most molecules
Catalyst	Speeds up the time it takes to reach equilibrium but does not change the position	–
