For the reaction `N_2O_4 harr 2NO_(2(g))`, the degree of dissociation at equilibrium is 0.2 at 1 atm. Then `K_p` will be

A

`1//2`

B

`1//4`

C

`1//6`

D

`1//8`

Text Solution

Verified by Experts

The correct Answer is:
C

`K_(P)=([P((2alpha)/(1+alpha))]^(2))/(P((1-alpha)/(1+alpha)))=P xx (4alpha^(2))/(1-alpha^(2))`
`K_(P)=1 xx (4 xx (0.2)^(2))/(1-(0.)^(2))=(1)/(6)`
