The relative volatility of a binary mixture at the Azeotropic composition is _______________________?
Correct answer: A. 1
- A. 1
- B. > 1
- C. 0
- D. ∞
Explanation
At an azeotrope, the vapour and liquid have the same composition, so their relative volatility is 1. Values above or below 1 indicate vapour-liquid composition differences and therefore no azeotropic condition at that composition.
