MCQ
The Haber process is operated at about 450 °C because:
Unit-9 Chemical Equilibrium
A the forward reaction is endothermic
B low temperature gives high yield but very slow rate
C high temperature increases the yield
D ammonia decomposes at high temperature
Explanation

Although a lower temperature favours more ammonia, the rate becomes too slow, so a moderate temperature gives an acceptable balance of rate and yield.
