Medium
For a binary nonideal A-B mixture exhibiting a minimum boiling azeotrope, the activity coefficients γi (i=A,B) must satisfy
- γA>1, γB>1
- BγA<1, γB>1
- CγA=1, γB=1
- DγA<1, γB<1
Explanation
A minimum-boiling azeotrope arises from positive deviations from Raoult's law — both activity coefficients exceed 1.
