Answer» At specific COMPOSITION methanol - acetone mixture will form MINIMUM boiling azeotrope and will show positive deviation from Raoult's law. At specific composition methanol - acetone mixture FORMS maximum boiling azeotrope and will show positive deviation from Raoult's law. At specific composition methanol - acetone mixture will form minimum boiling azeotrope and will show negative deviation from Raoult's law. At specific composition methanol - acetone mixture will form maximum boiling azeotrope and will show negative deviation from Raoult's law. Solution :Explanation : (A) (A-A) or (B-B) INTERACTIONS are stronger than the (A-B) interactions , where, A is methanol molecule & B represents a molecule of acetone. It means that in this solution molecules of A (or B) will FIND it easier to escape. This will increase the vapour from Rault.s law. Further, (B) Due to this positive deviation the methanol acetone mixture forms minimum boiling azeotrope.
