Solution

The correct option is A $75$
$N_{2} + 3 H_{2} ⇌ 2 {N H}_{3}$
$(g)$ $(g)$ $(g)$
At $28 g$ ${6 g}^{1}$ $0 g$
$t = 0$
$⇓$ $⇓$ $⇓$
1 mol 3 mol 0 mol
$A$ $1 - α$ $3 - 3 α$ $2 α$
$t = t_{e q}$
Given ( $2 α$ moles) weight $= 27.54$
$2 α = 1.62$
$α = 0.81$
$0.19$ $0.57$ $1.62$
$K_{C} = \frac{{(1.62)}^{2}}{{(0.57)}^{3} \times (0.19)} \approx 75$
