Question

dissociates as . 5 moles of  are placed in a 200 litre vessel which contains 2 moles of  and is maintained at 600 K. The equilibrium pressure is 2.46 atm. The equilibrium constant  for the dissociation of  is  (nearest integer).

(Assume ideal gas behaviour)

Step 1 — Find total moles at equilibrium:

Step 2 — Moles of each species:
Total = 10 mol;  = 2 mol (inert)  PCl system moles = 8 mol

Let  = moles of PCl₅ dissociated:
- PCl₅: , PCl₃: , Cl₂:   total PCl system =

Step 3 — Partial pressures:

Step 4 — :
