A liquid mixture that shows a large positive deviation from Raoult's law will form which kind of azeotrope?
Amaximum boiling azeotrope
Bno azeotrope at all
Cminimum boiling azeotrope
Dan ideal boiling azeotrope
Answer & Solution
Correct answer: C. minimum boiling azeotrope
1. Azeotropes form at large deviations from Raoult's law.
2. Large positive deviation means higher vapour pressure, hence lower boiling point at a specific composition.
3. So a large positive deviation gives a minimum boiling azeotrope (e.g. ethanol-water).
