Q. For the reaction, $PCl_{3}(g) + Cl_{2}(g) \rightleftharpoons PCl_{5}(g)$ the position of equilibrium can be shifted to the right by
A) Doubling the volume
B) Increasing the temperature
C) Addition of equimolar quantities of $PCl_{3}\ and\ PCl_{5}$
D) Addition of $Cl_{2}$ at constant volume
Explanation
(d)
$PCl_{3}(g) + Cl_{2}(g) \rightleftharpoons PCl_{5}(g)$
According to Le-Chatelier’s principle, on increasing volume of a reactant, the reaction proceeds in forward direction. Hence, on addition of $Cl_{2}$ to above reaction, the equilibrium will shift to the right.
