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.

Answer the question (given below) which are based on the following diagra. 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 pressure of both A and B are greater than predicted by Raoult's law. The dashed lines lines represented the plots for ideal solutions. A : This is observed when A...B attraction 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 is called azeotropic mixture Select correct facts

`{:("Attraction" A...B,DeltaH_("mix"),DeltaV_("mix"),B.P),("Larger than average of" A...A .B..B"attraction",+ve,+ve,"larger than expected"):}`

`{:("Attraction" A...B,DeltaH_("mix"),DeltaV_("mix"),B.P),("As in" (a),-ve,-ve,"As in" (a)):}`

`{:("Attraction" A...B,DeltaH_("mix"),DeltaV_("mix"),B.P),("Smaller than average of" A...A..B..B "attraction",+ve,+ve,"Smaller than expected"):}`

`{:("Attraction" A...B,DeltaH_("mix"),DeltaV_("mix"),B.P),("As in"(c),-ve,-ve,"As in"(c)):}`

There is positive deviation from Raoult's law

Boiling point has been lowered

Force of attraction between `A` and `B` is smaller than that between `A` and `A` or between `B` and `B`.

All the above statements are correct.
