For reacrtion 2NOC1(g) hArr 2NO(g) + C1(...

For reacrtion `2NOC1(g) hArr 2NO(g) + C1_(2)(g)` , `K_(c)` at `427^(@)C` is `3xx10^(-6)` L `mol^(-1)`. The value of `K_(p)` is nearly

A

`7.50 xx10^(-5)`

B

`2.50 xx10^(-5)`

C

`2.50 xx10^(-4)`

D

`1.72 xx10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`2NOCl_((g))=2NO_((g))+Cl_(2(g))`
`K_p = K_c(RT)^(Deltan_g)`
`K_p =3 xx10^(-6)(0.0821 xx 700) = 172.41 xx10^(-6)`
`= 1.72 xx10^4`
