For the reaction: `2NOCl(g) hArr 2NO(g) +Cl_(2)(g), K_(c)` at `427^(@)C` is `3xx10^(-6) L mol^(-1)`. The value of `K_(p)` is

A

`7.50xx10^(-5)`

B

`2.50xx10^(-5)`

C

`2.50xx10^(-4)`

D

`1.75xx10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`2NOCl_((g))=2NO_((g))+Cl_(2(g))`
`K_(p)=K_(C) cdot (RT)^(6n)`
`K_(p)=3xx10^(-6)(0.0821xx700)=172.41xx10^(-6)`
`=1.72xx10^(-4)`
