In an evacuated vessel of capacity 112 L, 4 moles of $Ar\left(g\right)$ and 5 moles of $PC{l}_5\left(g\right)$ were introduced and the temperature is maintained at $273°C.$ At equilibrium, the total pressure of the mixture was found to be 4.8 atm.

$K_P$ for the reaction : $PC{l}_5\left(g\right)\rightleftharpoons PC{l}_3\left(g\right)+C{l}_2\left(g\right)$ is 2.7 atm

At equilibrium, the total moles of gases are 12

The degree of dissociation of $PC{l}_5\left(g\right)$ into $PC{l}_3\left(g\right)$ and $C{l}_2\left(g\right)$ is 0.6

On removing Ar(g) from the equilibrium mixture at constant pressure and temperature, the extent of dissociation of $PC{l}_5$ will increase
