The reaction , `SO_(2) + Cl_(2) hArr SO_(2)Cl_(2)` is exothermic and reversible . A mixture of `SO_(2)(g) , Cl_(2) hArr SO_(2) Cl_(2)(g) ` 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

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

Answer

C

Explanation

`SO_(2) +Cl_(2) hArr SO_(2)Cl_(2) + "Heat"`.
On adding `SO_(2)` , the equilibrium will shift forward , i.e., more heat will be evolved . So temperature will increase .
