`K_(p)` and `K_(c)` are inter related as
`K_(p)=K_(c)(RT)^(Deltan)`
Answer the following questions:
In which of the following equilibria `K_(p)` is less than `K_(c)`?

Options

A. `N_(2)O_(4)hArr2NO_(2)`
B. `2HI hArrH_(2) + I_(2)`
C. `2SO_(2) + O_(2)hArr2SO_(3)`
D. `N_(2) + O_(2)hArr 2NO`

Answer

C

Explanation

`K_(p) = K_(c)(RT)^(Delta n)`
`Delta n = - 1` for reaction `2SO_(2) + O_(2)hArr2SO_(3)`
So for this reaction `K_(p)` is less than `K_(c)`.
