According to Le Chatelier's principle, when the volume of the container is increased, the system will shift in the direction that reduces the number of moles of gas. In the reaction PCl5(g) ⇌ PCl3(g) + Cl2(g), there are 2 moles of gas on the left and 1 mole of gas on the right. Therefore, the equilibrium will shift to the right to decrease the number of moles of gas, resulting in a decrease in the amount of PCl5 present.
