MCQ
In the Haber process, increasing the temperature decreases the yield of ammonia because:
Unit-9 Chemical Equilibrium
A the forward reaction is exothermic
B the forward reaction is endothermic
C ammonia freezes at high temperature
D the catalyst stops working
Explanation

The formation of ammonia is exothermic, so high temperature favours the reverse endothermic decomposition and reduces the yield.
