Solution

The correct option is B increases the dissociation of PCl5
For the reaction PCl5PCl3+Cl2, the forward reaction occurs with an increase in the number of moles from 1 to 2. Also, the reverse reaction occurs with a decrease in the number of moles from 2 to 1.
When inert gas is added at constant pressure, the equilibrium will shift in the direction in which there is an increase in the number of moles of gases.
Thus, the addition of inert gas at constant pressure will increase the dissociation of PCl5.

Option B is correct.
