Assertion : In the dissociation of PCl(5...

Assertion : In the dissociation of `PCl_(5)` at constant pressure and temperature addition of helium at equilibrium increases the dissociation of `PCI_(3).`
Reason : Helium reacts with Cl, and hence shifts the equilibrium in forward direction.

A

Statement 1 is True, statement 2 is True, Statement 2 is correct explanation for Statement 1.

B

Statement 1 is True, statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, statement 2 is false.

D

Statement 1 is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
C
Helium is an inert gas and hence does not react with `Cl_(2)`. However to keep the pressure constant on addition of helium, volume of the system will increase which will favour forward reaction.
