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

`2.4xx10^(-3)`

B

`4.0xx10^(-6)`

C

`4xx10^(-6)xx (RT)^(2)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`N_(2)+O_(2)hArr2NO`
for this reaction `Deltan = 0`
Since `K_(p)=K_(c)(RT)^(Deltan)thereforeK_(p)=K_(c)`
