Answer 1

3.All the answers that are given by you are correct. But the point b you have shown for the vapour composition 20%toluene and 80% benzene should be slightly left than you have shown in the diagram so that when you will draw a straight line horizontally to specify the liquid composition, you can get the corresponding liquid composition exactly at 40% toluene and 60% benzene.

1.From the graph it is clearly seen that the boiling point of 50% toluene and benzene is 90°C.

2.The point a in the figure is not shown clearly. So if it is the point that is shown by you at 30% toluene and 70℅ benzene vapour composition ,then all answers are right.
