Temperature and ammonia yield
The forward reaction to produce ammonia is exothermic.
Explain the effect of increasing the temperature on the yield of ammonia.
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 increasing temperature shifts the system in the endothermic direction.
Full-mark answer
The yield of ammonia decreases because increasing temperature favours the endothermic direction, so the equilibrium shifts away from ammonia.
