Vedclass · Answer

(C) When an inert gas is added to a system at equilibrium at constant volume,the total pressure of the system increases.However,the partial pressures or concentrations of the reacting species ($NH_3$ and $H_2S$) remain unchanged because the volume of the container and the number of moles of the reactants and products do not change.Since the reaction quotient $Q_c$ remains equal to the equilibrium constant $K_c$,there is no shift in the equilibrium position.Therefore,the equilibrium remains unaffected.

Some inert gas is added at constant volume to the following reaction at equilibrium:
$NH_4HS_{(s)} \rightleftharpoons NH_{3(g)} + H_2S_{(g)}$
Predict the effect of adding the inert gas.
