Question

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. `7.5 xx 10^(-5)`
B. `2.50 xx 10^(-5)`
C. `2.5 xx 10^(-4)`
D. `1.75 xx 10^(-4)`

Answer 1

Correct Answer - D
`2 NOCI(g) hArr 2 NO(g) + CI_(2) (g)`
`K_(p) =K_(c) (RT)^(Deltan) =3xx 10^(-6) (0.0821 xx 700)`
`=1.72 xx 10^(-4)`
