15 cm3 of liquid 'x' and 20 cm3 of liquid 'y' are mixed at 20ºC and the volume of solution was measured to be 35.1 cm3 then correct reaction is

given    Vmix= 35.1ccVA=15  ,   VB=20cc Vmix.is greater than expected , so It is a non ideal solution(acc. to Raoult's law)Hence(1)         It shows positive deveation(2) Heat is absorbed,   (3) Vapour pressure will be more than ideal solution
