Solution

The correct options are
B $C O (g) + {C l}_{2} (g) ⇌ C O {C l}_{2} (g)$
D $N_{2} (g) + 3 H_{2} (g) ⇌ 2 {N H}_{3} (g)$
The following reactions have $K_{p} < K_{c}$ .
$C O (g) + {C l}_{2} (g) ⇌ C O {C l}_{2} (g)$ $Δ n = 1 - (1 + 1) = - 1$
$N_{2} (g) + 3 H_{2} (g) ⇌ 2 {N H}_{3} (g)$ $Δ n = 2 - (1 + 3) = - 2$
For such reactions $Δ n < 0$
$K_{p} = K_{c} (R T)^{Δ n}$
