The equilibrium constant for the reaction
`N_2+3H_2 hArr 2NH_3` is K , then the equilibrium constant for the equilibrium `2NH_3hArr N_2+3H_2` is

A

1/K

B

`1//K^2`

C

`sqrt(K)`

D

`1/sqrtK`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_1` for `N_2 +3H_2hArr 2NH_3`
`K_2` for `NH_3 hArr 1/2 N_2 +3/2H_2`
`K_1 = ([NH_3]^(2))/([N_2][H_2]^(3))xx([N_2]^(1//2)[H_2]^(3//2))/([NH_3])`
`K_1 xx K_2 =1/K_2 ,K_2 =1/sqrt(K_1)`
