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.
