Vedclass · Answer

(D) When an inert gas like xenon is added to a gaseous equilibrium system at constant $T$ and $P$,the total volume of the system increases.This leads to a decrease in the partial pressure of each reacting species.According to Le Chatelier's principle,the system shifts in the direction that increases the total number of moles of gas.In the reaction $PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$,the number of moles of products $(2)$ is greater than the number of moles of reactants $(1)$.Therefore,the equilibrium shifts in the forward direction.As a result,the concentration of $PCl_5$ decreases,while the concentrations of $PCl_3$ and $Cl_2$ increase.

In the following system,$PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$ at equilibrium,upon addition of xenon gas at constant $T$ & $p$,the concentration of
