PCl₅ dissociates as

PCl₅(g) $?$  PCl₃ (g) + Cl₂(g)

5 moles of PCl₅ placed in a 200 litre vessel which contains 2 moles of N₂ and is maintained at 600K. The equilibrium pressure is 2.46 atm. The equilibrium constant Kp for the dissociation of PCl₅ is ____________ * 10^-3g.  (nearest integer).

(Given R = 0.082 L atm K^-1 mol^-1; Assume ideal gas behavior)
