Consider the following equilibrium
`PCl(g) hArr PCl_(3)(g) + Cl_(2)(g)` in a closed container. At a fixed temperature, the volume of the reaction container is halved. For this change, which of the following statements holds true regarding the equilibrium constant `(K_(p))` and degree of dissocitation `(alpha) ` ?

A

Neither `K_p` nor `alpha` changes

B

Both `K_p` and `alpha` change

C

`K_p` changes, but `alpha` does not change

D

`K_p` does not change, but `alpha` changes

Text Solution

Verified by Experts

The correct Answer is:
D
`K_(P)` does not change with volume on decreasing volume, equilibrium shifts `:. alpha` changes
