Consider the reaction (g) (g) + (g) in a closed container at equilibrium. At a fixed temperature what will be the effect of adding more on the equilibrium concentration of (g) ?

Question

Consider the reaction $PCl_5$ (g) $PCl_3$ (g) + $Cl_2$ (g) in a closed container at equilibrium. At a fixed temperature what will be the effect of adding more $PCl_5$ on the equilibrium concentration of $Cl_2$ (g) ?

Prashant Kotian · Accepted Answer

Correct answer: B. According to Le-Chatelier's principle, when the reactant 5 PCl is added in the reaction, then the reaction is favoured in the forward direction which results in the increase in the concentration of the product i.e. 2 Cl .
