Question

The reaction, $SO _{2}+ Cl _{2} \longrightarrow SO _{2} Cl _{2}$ is exothermic and reversible. $A$ mixture of $SO _{2}( g ), Cl _{2}( g )$ and $SO _{2} Cl _{2}(l)$ is at equilibrium in a closed container. Now a certain quantity of extra $SO _{2}$ is introduced into the container, the volume remaining the same. Which of the following is/are true?

• A. The pressure inside the container will not change.
• B. The temperature will not change.
• C. The temperature will increase.
• D. The temperature will decrease.

Answer 1

Answer: (C)

The temperature will increase.

Answer 2

By addition of $SO_2$, equilibrium will shift to RHS which is exothermic. Hence temp, will increase.
