The equilibrium constant for the reaction
`N_(2)(g)+O_(2)(g) hArr 2NO(g)`
at temperature T is `4xx10^(-4)`.
The value of `K_(c)` for the reaction
`NO(g) hArr 1/2 N_(2)(g)+1/2 O_(2)(g)`
at the same temperature is

A

25

B

50

C

75

D

100

Text Solution

Verified by Experts

The correct Answer is:
B
`N_(2)(g) + O_(2)(g) rarr 2NO(g) K_(1)`
` NO(g) rarr 1/2N_(2)(g) + 1/2O_(2)(g) K_(2)`
`K_(1) = 1/K_(2)^(1//2)`
