The reaction, $\mathrm{SO}_{2}+\mathrm{Cl}_{2} \longrightarrow \mathrm{SO}_{2} \mathrm{Cl}_{2}$ is exothermic and reversible. A mixture of $\mathrm{SO}_{2}(\mathrm{~g})$, $\mathrm{Cl}_{2}$ (g) and $\mathrm{SO}_{2} \mathrm{Cl}_{2}(\mathrm{l})$ is at equilibrium in a closed container. Now a certain quantity of extra $\mathrm{SO}_{2}$ is introduced into the container, the volume remaining the same. Which of the following is are true?
The pressure inside the container will not change.
The temperature will not change.
The temperature will increase.
The temperature will decrease.
Solution
By addition of $\mathrm{SO}_{2}$ equilibrium will shift to RHS which is exothermic. Hence temperature will increase.
