Temperature and equilibrium yield
The forward reaction is exothermic.
Explain the effect of increasing the temperature on the yield of ammonia gas produced at equilibrium.
Write your answer first. You can study the marking guidance whenever you need it.

Marking points
- 1 State that the yield of ammonia decreases.
- 2 Explain that the system shifts in the endothermic direction to counteract the temperature increase.
Full-mark answer
The yield of ammonia decreases. Increasing temperature favours the endothermic direction, so the equilibrium shifts away from ammonia to counteract the change.
