Assertion: Association of an inert gas at constant pressure to dissociation equilibrium of `PC1_(5) hArr PC1_(3) + C1_(2)` favours forward reaction.
Reason: `K_(c) =(alpha^(2))/(V(1 - alpha))` for the dissociation equilibrium of `PC1_(5)` where `alpha` is degree of dissociation of `PC1_(5)` .

A

If both assertion and reason are true and the reason is the true explanation of the assertion.

B

If both the assertion and reason are true but the reason is not the correst explanation of assertion.

C

If the assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Inert gas addition at constant pressure leads to an increase in volume. To have `K_(c)` constant `'alpha'` must increase.
