Chemistry - Chemical Equilibrium Question with Solution | TestHub

${\text{NH}}_4\text{HS}\left(\text{s}\right)\rightleftharpoons \underset{\text{P}}{{\text{NH}}_3\left(\text{g}\right)}+\underset{\text{P}}{{\text{H}}_2\text{S}\left(\text{g}\right)}$
Equilibrium pressure is 2P here
$2\mathrm{P}=0.660$
$\mathrm{P}=0.330$
${\mathrm{K}}_{\mathrm{p}}={\mathrm{P}}_{\mathrm{N}{\mathrm{H}}_3}.{\mathrm{P}}_{{\mathrm{H}}_2\mathrm{S}}$
$=0.33\times 0.33=0.109(\mathrm{a}\mathrm{t}\mathrm{m}{)}^2$
