Q. $N_{2} + 3H_{2} \rightleftharpoons 2NH_{3} + heat$. 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
Explanation
(a)
$N_{2} + 3H_{2} \rightleftharpoons 2NH_{3} + heat$
It is an exothermic reaction, so high temperature favours backward reaction. Hence, equilibrium is shifted towards the left.
