In which of the following reactions is `K_(p) lt K_(C)`?

Options

A. `I_(2)(g) hArr 2l(g)`
B. `2BrCI(g) hArr CI_(2)(g) +Br_(2)(g)`
C. `CO(g) +3H_(2)(g) hArr CH_(4)(g)+H_(2)O(g)`
D. All of the above

Answer

C

Explanation

We have, `K_(p) = K_(C) (RT)^(Deltan)`
For `CO(g) + 3H_(2)(g) hArr CH_(4)(g)+H_(2)O(g)`
`Deltan =- 2`
`K_(p) = (K_(C))/((RT)^(2))`
`:. K_(p) lt K_(C)`
