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 :

Answer the questions (given below) which are based on the following diagram: vapour pessure diagram for real solution of two liquids A and B that exhibit a negative deviation from Raoult's law. The vapour pressure of both A and B are less than predicted by Raoult's law. The dashed lines represent the plots for ideal solutions. Solution containing components A and B show this type of deviation from ideal behaviour when:

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. Total vapour pressure of mixture of 1 mol of volatile component A(P_(A)^(@)=100 mmHg) and 3 mol of volatile component B(P_(B)^(@)=60 mmHg) is 75 mm . For such case:
