Q. The equilibrium reaction $PCl_{5}\left(\right.s\left.\right)\rightleftharpoonsPCl_{3}\left(\right.s\left.\right)+Cl_{2}\left(\right.g\left.\right)$ is carried in a closed vessel. What is the effect on equilibrium concentration of $Cl_{2}\left(\right.g\left.\right)$ by adding $PCl_{5}$ at constant temperature?

Solution:

On adding more $PCl_{5}$ , equilibrium shifts forward, hence concentration of $Cl_{2}\left(\right.g\left.\right)$ increases.
