A binary liquid Azeotropic mixture has boiling point higher than either of the components, when it shows ______________ deviation from Raoult's Law?
Correct answer: B. Negative
- A. Positive
- B. Negative
- C. No
- D. None of these
Explanation
Negative deviation from Raoult’s law lowers the total vapour pressure, so the mixture boils at a temperature higher than either pure component and forms a maximum-boiling azeotrope. Positive deviation produces a minimum-boiling azeotrope.
