Consider the following equilibrium system:
`2SO_2(g)+O_2(g) hArr 2SO_3(g)`
Some inert gas is added to the above system at constant volume. Predict which of the following is true?

A

More of `SO_3` is produced.

B

Less `SO_2` is produced.

C

Addition of inert gas does not affect equilibrium.

D

System moves to new equilibrium position which can not be predicted theoretically.

Text Solution

Verified by Experts

The correct Answer is:
C
If the gas that is introduced (at constant volume) is notinvolved in the reaction, the partial pressure of each reacting has remains constant. So the system remains at equilibrium. However, the total pressure of a gaseous system is raised by pumping an inert gas.
