Equilibrium constants K(1) and K(2) for ...

Equilibrium constants `K_(1)` and `K_(2)` for the following equilibria
`NO(g) +1//2O_(2)(g) overset(K_(1))(hArr) NO_(2)(g)` and `
`2NO_(2)(g) overset(K_(2))(hArr)2NO(g)+O_(2)(g)`
are related as

A

`K_(1) =sqrt(K_(2))`

B

`K_(2) =(1)/(K_(1))`

C

`K_(1) = 2K_(2)`

D

`K_(2) =(1)/(K_(1)^(-2))`

Text Solution

Verified by Experts

The correct Answer is:
D
Equation (2) can be obtained by multiplying equation (1) with 2 and reversing it . Therefore `K_(2) " and " K_(1)` are related to each other as : `K_(2) =(1)/(K_(1)^(-2))`
