For the equilibrium : LiCl.3NH3 (s) ⇌ LiCl.NH3 (s) + 2NH3 (g) . Katp = 9 atm2 at 27° C. A 4.92 litre vessel contains 0.1 mole of LiCl.3NH3 . The number of moles of NH3 should be added to the flask at this temperature to drive theback ward reaction for completion is (0.2 × y) . The value of ‘y’ is-----
