Question

$N_2+3H_2\rightleftharpoons 2N{H}_3+$heat. What is the effect of the increase of temperature on the equilibrium of the reaction?

• A. Equilibrium is shifted to the left
• B. Equilibrium is shifted to the right
• C. Equilibrium is unaltered
• D. Reaction rate does not change

Answer 1

The correct option is A Equilibrium is shifted to the left

Increase in temperature favours the endothermic reaction. In the given reaction, the backward reaction is an endothermic reaction. So the backward reaction is favoured, so the equilibrium shifts towards left.

Hence, option A is correct.
