PCl 5 dissociates as PCl 5 g ⇌ 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___ × 10 - 3 . (nearest integer) (Given: R = 0 . 082 L atm K - 1 mol - 1 ; Assume ideal gas behaviour)
