Embibe Experts Solutions for Chapter: Equilibrium, Exercise 1: KCET (UG) 2021

The relationship between ${\mathrm{K}}_{\mathrm{p}}$ and ${\mathrm{K}}_{\mathrm{c}}$ is ${\mathrm{K}}_{\mathrm{p}}={\mathrm{K}}_{\mathrm{c}}{\left(\mathrm{RT}\right)}^{\mathrm{\Delta n}}$. What would be the value of $\mathrm{\Delta n}$ for the reaction, ${\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{s}\right)\rightleftharpoons {\mathrm{NH}}_3\left(\mathrm{g}\right)+\mathrm{HCl}\left(\mathrm{g}\right)$ ?

For the reaction
$\mathrm{A}\left(\mathrm{g}\right)+\mathrm{B}\left(\mathrm{g}\right)\rightleftharpoons \mathrm{C}\left(\mathrm{g}\right)+\mathrm{D}\left(\mathrm{g}\right);∆\mathrm{H}=-\mathrm{Q} \mathrm{kJ}$
The equilibrium constant cannot be disturbed by
