The reaction, $\mathrm{N}_2(g)+3 \mathrm{H}_2(g) \rightleftharpoons 2 \mathrm{NH}_3(g)$ is exothermic and reversible. A mixture of $\mathrm{N}_2(g), \mathrm{H}_2(g)$ and $\mathrm{NH}_3(g)$ is at equilibrium in a closed container. When a certain quantity of extra $\mathrm{H}_2(g)$ is introduced into the container, while keeping the volume constant, then which statement among the following is true?
  1. The pressure inside the container will not change.
  2. Equilibrium condition will not change.
  3. The temperature will increase.
  4. The temperature will decrease.

Solution

Since, the reaction is exothermic and volume is kept constant. So, the temperature will increase.
