For a homogeneous equilibrium of gases,which of the following changes in reaction conditions will not alter the equilibrium concentrations?

Question

Quizplus · Accepted Answer

Adding an inert gas does not change the concentrations of reactants or products in the reaction mixture, and therefore does not affect the equilibrium concentrations. Inert gases do not participate in the chemical reaction and thus do not disturb the equilibrium. On the other hand, adding reactants or products will shift the equilibrium to one direction, decreasing the concentration of the added substance and increasing the concentration of the other substances to re-establish the equilibrium. Similarly, decreasing the pressure or volume will also shift the equilibrium to the side with fewer moles of gas, while increasing the temperature will shift the equilibrium in the direction that absorbs heat (endothermic) or releases heat (exothermic).
