Q. In the Haber's process, for manufacturing ammonia, the reaction $N _{2}( g )+3 H _{2}( g ) \rightleftharpoons 2 NH _{3}( g )$ is performed at $200\, atm$ pressure in the presence of a catalyst and at a temperature of $500^{\circ} C$. This is considered as optimum temperature for the process because

Equilibrium

Solution:

The optimum conditions of a reaction are ascertained by Le Chatelier's principle. An exothermic reaction when performed at a moderately low temperature will move in a direction so as to undo the effect and will lead to more product formation. Moreover, a catalyst only enhances the speed of the reaction. It does not increase the product.
