If a substance (or heat) is ADDED shift AWAY from that substance (or heat) 2. If a substance (or heat) is TAKEN shift TOWARDS that substance (or heat) 3. If pressure is added, there is less volume/room for moles. Shift towards side with less moles. 4. If pressure is relieved, there is more room. Shift towards the side with more moles. 5. Catalysts speed up the forward AND reverse reaction. Therefore equilibrium is unchanged. 6. At equilibrium RATES are equal. Not amount! Circle which direction the equilibrium will shift towards to relieve the stress and cite the rule used: 2NH3(g) N2(g) + 3H2(g) + heat Rule # Ammonia is added left right no effect _____ Nitrogen is added left right no effect _____ Hydrogen is added left right no effect _____ Heat is added left right no effect _____ Ammonia is removed left right no effect _____ Nitrogen is removed left right no effect _____ Hydrogen is removed left right no effect _____ Heat is removed left right no effect _____ Pressure is increased left right no effect _____ Pressure is decreased left right no effect _____ A catalyst is added left right no effect _____ Circle what will happen to the Nitrogen to relieve the stress: N2(g) + 3H2(g) + heat 2NH3(g) Ammonia is removed increase decrease remain the same
