Question

We know that the relationship between $K_c$ and $K_p$ is
$
K_p=K_c(R T)^{\Delta n}
$
What would be the value of $\Delta n$ for the reaction :
$
\mathrm{NH}_4 \mathrm{Cl}_{(s)} \rightleftharpoons \mathrm{NH}_{3(\mathrm{~g})}+\mathrm{HCl}_{(\mathrm{g})} ?
$

Professor PC Thomas Classes · Answer

(d): For the reaction : $\mathrm{NH}_4 \mathrm{Cl}_{(s)} ightleftharpoons \mathrm{NH}_{3(g)}+\mathrm{HCl}_{(g)} \ \Delta n_g=n_{(	ext {gaseous products })}-n_{(	ext {gaseous reactants })}=2-0=2$
