Le Chatelier’s Principle: Temperature Changes on Equilibrium (OCR GCSE Chemistry A (Gateway Science Suite)): Flashcards

Equilibrium shifts to oppose temperature changes

Shifts to endothermic side (absorbs heat)

Shifts to exothermic side (releases heat)

Endothermic side

Exothermic side

To absorb excess heat and reduce temperature

To release heat and increase temperature

Exothermic (forward reaction releases heat)

Shifts left to reactants, decreases $NH_3$

Shifts right to products, increases $NH_3$
