Welcome to Chem Zipper.com......: Liquid A and B forms an ideal solution and initial vapour pressure of A and B are P°A= 0.4 atm and P°A= 0.6 atm respectively. In a cylinder piston arrangement, 2 mole vapour of A and 3 mole vapour of B is collected at 0.42 atm.

Liquid A and B forms an ideal solution and initial vapour pressure of A and B are P°A= 0.4 atm and P°A= 0.6 atm respectively. In a cylinder piston arrangement, 2 mole vapour of A and 3 mole vapour of B is collected at 0.42 atm.

(1) predict wheather the vapour will condense or not ?
(2) If the vapours are  compared slowly and isothermally at what  pressure F drop of liquid will form?
(3) If initial volume of vapour was 10 litre , at what volume first drop of liquid is form?
(4) What is the composition of first drop of liquid formed?
(5) If vapour pressure are further compressed. At what  pressure  almost complete condensation of vapour will occure?
(6) Determine the composition of last traces of vapours remains?
(7) What is the composition of system at 0.55 atm pressure?
(8) Determine the composition of liquid and vapour formed  at 0.51 atm also  calculate the moles of liquid of A and B in liquid and vapour formed ?
(9) At what pressure half of the total amount of vapour will condense?
