Question

For reaction `2NOCl_((g))hArr2NO_((g))+Xl_(2(g)), K_(c)at 427^(@)C`is `3xx10^(-6)Lmol^(-1).` The value of `K_(p)` is nearly
A. `7.50xx10^(-50)`
B. `2.50xx10^(-50)`
C. `2.50xx10^(-4)`
D. `1.72xx10^(-4)`

Answer 1

Correct Answer - D
`2NOCl_((g))=2NO_((g))+Cl_(2(g))`
`K_(p)+K_(c)(RT)^(Deltan)`
`K_(p)=3xx10^(-6)(0.0821xx700)=172.41xx10^(-6)=1.72xx10^(-4)`
