The reaction, SO ₂+ Cl ₂ 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?

Options

  1. AThe pressure inside the container will not change.
  2. BThe temperature will not change.
  3. CThe temperature will increase.
  4. DThe temperature will decrease.

Correct answer

C. The temperature will increase.

Step-by-step solution

Byaddition of SO ₂ , equilibrium will shift to RHS which is exothermic. Hence temp, will increase.
