Le Chatelier's principle for temp changes

Equilibrium shifts to oppose the temp change

Temp increase: equilibrium shift direction

Towards endothermic side (absorbs heat)

Side that absorbs heat

Endothermic side

Temp decrease: equilibrium shift direction

Towards exothermic side (releases heat)

Side that releases heat

Exothermic side

Ammonia formation: forward reaction type

Exothermic (releases heat)

Ammonia: equilibrium shift when temp increases

Shifts left to reactants (endothermic side)

Ammonia: NH3NH_3 conc. when temp increases

Decreases

Ammonia: equilibrium shift when temp decreases

Shifts right to products (exothermic side)

Ammonia: NH3NH_3 conc. when temp decreases

Increases
