PCl5 dissociates as PCl5(g) $\rightleftharpoons$ PCl3(g) + Cl2(g) 5 moles of PCl5 are placed in a 200 litre vessel which contains 2 moles of N2 and is maintained at 600 K. The equilibrium pressure is 2.46 atm. The equilibrium constant Kp for the dissociation of PCl5 is __________ $\times$ 10$-$3. (nearest integer) (Given : R = 0.082 L atm K$-$1 mol$-$1; Assume ideal gas behaviour)

Question

PCl₅ dissociates as

PCl₅(g) $\rightleftharpoons$ PCl₃(g) + Cl₂(g)

5 moles of PCl₅ are placed in a 200 litre vessel which contains 2 moles of N₂ and is maintained at 600 K. The equilibrium pressure is 2.46 atm. The equilibrium constant K_p for the dissociation of PCl₅ is __________ $\times$ 10^$-$3. (nearest integer)

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