Vedclass · Answer

(D) For the reaction: $PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$$1$. At constant pressure: The addition of an inert gas like helium increases the volume of the system. According to Le Chatelier's principle,the equilibrium shifts towards the side with a greater number of moles of gas,which is the forward direction. Thus,more $PCl_3$ and $Cl_2$ are produced.$2$. At constant volume: The addition of an inert gas does not change the partial pressures or concentrations of the reacting species. Therefore,the equilibrium remains unaffected.Since the condition (constant pressure or constant volume) is not specified,in standard textbook problems,if not mentioned,it is often assumed to be at constant volume,or the question is considered ambiguous. However,based on the options provided,if the pressure is constant,$A$ is correct; if the volume is constant,$D$ is correct. In many competitive contexts,if the condition is not specified,the addition of an inert gas at constant volume is the standard assumption,leading to $D$.

The effect of the addition of helium gas to the following reaction in an equilibrium state is:
$PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$
