A system at equilibrium is described by ...

A system at equilibrium is described by the equation
`SO_(2)Cl_(2) hArr SO_(2)+Cl_(2),Delta H =+ve`.
When `Cl_(2)` is added to the equilibrium mixture at constant volume, the temperture of the system

A

increases

B

decreases

C

does not change

D

first increases and then decreases.

Text Solution

Verified by Experts

The correct Answer is:
A
Adding `Cl_(2)` shifts the equilibrium in the backward direction . As the backward reaction is exothermic, adding `Cl_(2)` at equilibrium increases the temperature.
