Which one of the following statement is correct regarding minimum boiling azeotrope ?


Azeotropic mixture is a constant boiling mixture. At certain concentration, both liquids boil at same temperature.It is not possible to separate them by fractional distillation.

Minimum boiling Azeotrope means lesser boiling point than expected from Raoult's law ;

Higher vapour pressure than expected from Raoult's law ;

A-B interactions are weaker than A-A and B-B interactions ;

Repulsions dominate; It shows positive deviations from Raoult's law

Hmix=+ve ; Vmix=-ve ; Gmix=-ve ; Smix=+ve ;
