Solution

The correct options are
A $2 N O C l (g) ⇌ 2 N H (g) + C l_{2} (g)$
B $N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g)$
D $N_{2} O_{4} (g) ⇌ 2 N O_{2} (g)$
As we know,
$K_{p} = K_{c} (R T)^{Δ n}$ ,
when $Δ n \neq 0, K_{p} \neq K_{c}$
$2 N O C l (g) ⇌ 2 N H (g) + C l_{2} (g)$ $Δ n = 1$
$N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g)$ $Δ n = - 2$
$N_{2} O_{4} (g) ⇌ 2 N O_{2} (g)$ $Δ n = 1$
$H_{2} (g) + C l_{2} (g) ⇌ 2 H C l (g)$ $Δ n = 0$
