$PCl _{5}( g ) \rightleftharpoons PCl _{3}( g )+ Cl _{2}( g )$
$5$ moles of $PCl _{5}$ are placed in a $200$ $litre$ vessel which contains $2\, moles$ of $N _{2}$ and is maintained at $600 \,K$. The equilibrium pressure is $2.46 \,atm$. The equilibrium constant $K _{ p }$ for the dissociation of $PCl _{5}$ is $......\,\times 10^{-3}$. (nearest integer)
(Given: $R =0.082\, L \,atm \,K ^{-1} \,mol ^{-1}$ : Assume ideal gas behaviour)
