Adding reactant to an equilibrium

shifts to the right

removing reactant from an equilibrium

shifts to the left

removing product from an equilibrium

shifts to the right

for an endothermic rxn, increasing temperature to an equilibrium

shifts to the right

for an exothermic rxn, increasing temperature to an equilibrium

shifts to the left

Increasing pressure on an equilibruim rxn

shifts toward the side with fewer moles of gas

Decreasing pressure on an equilibrium rxn

shifts toward the side with more moles of gas

Increasing volume on an equilibrium rxn

shifts toward the side with more moles of gas

Decreasing volume on an equilibrium rxn

shifts toward the side with fewer moles of gas

What if both sides have equal moles of gas?

Volume and Pressure do not affect equilibrium
