The reaction, $\mathrm{SO}_{2}+\mathrm{Cl}_{2} \longrightarrow \mathrm{SO}_{2} \mathrm{Cl}_{2}$ is
exothermic and reversible. A mixture of $\mathrm{SO}_{2}(\mathrm{~g})$, $\mathrm{Cl}_{2}(\mathrm{~g})$ 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 correct answer is: The temperature will increase.
Byaddition of $\mathrm{SO}_{2}$, equilibrium will shift to RHS which is exothermic. Hence temp, will increase.
