Question

The reaction, $4S{O}_2+C{l}_2\to S{O}_{2}C{l}_{2}4$ is exothermic and reversible. A mixture of $S{O}_{2(g)},C{l}_{2(g)}$ and $S{O}_{2}C{l}_{2(l)}$ is at equilibrium in a closed container. Now, a certain quantity of extra $S{O}_2$ is introduced into the container, the volume remaining the same. Which of the following is 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)

On adding $S{O}_2$, equilibrium shifts in forward. As it is exothermic reaction, temperature will increase.
