QuestionWhat happens to the equilibrium when $\mathrm{H}_{2} \mathrm{~S}$ gas is removed from this reaction?
$$\mathrm{NH}_{4} \mathrm{HS}(\mathrm{s}) \rightleftharpoons \mathrm{NH}_{3}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{~S}(\mathrm{~g})$$
A. Shift left, $\mathrm{NH}_{3}$ decreases.
B. Shift right, $\mathrm{NH}_{3}$ increases.
C. Shift left, $\mathrm{NH}_{3}$ increases.
D. Shift right, $\mathrm{NH}_{3}$ decreases.
