In the dissociation of `PCl_(5)` as
`PCl_(5)(g) hArr PCl_(3)(g)+Cl_(2)(g)`
If the degree of dissociation is `alpha` at equilibrium pressure P, then the equilibrium constant for the reaction is

A

0.25

B

0.3

C

0.5

D

1

Text Solution

Verified by Experts

The correct Answer is:
C
`PCl_(5) Leftrightarrow PCl_(5)+Cl_(2)`
`{:(,"Initial",1,0,0),(,"At equ.", 1-0.5,0.5, 0.5):}`
`K_(c)=(0.5 xx 0.5)/(0.5)=0.5`
