Answer the questions (given below) which are based on the following diagram ?
Consider some facts about the above phase diagram. Vapour pressure diagram for real solutions of two liquids A and B that exhibit a positive deviation from Raoult's law. The vapour presssure of both A and B are greater than predicted by Raoult's law. The dashed lines represented the plots for ideal solutions.
A : This is obserbed when A...B attractions are greater than average of A...B and B.....B attraction :
B : `DeltaH_(mix) = +ve, DeltaV_(mix) = +ve`
C : Boiling point is smaller than expected such that vaporisation is increased
D : Mixture can from azeotropic mixture Select correct facts.
