If two liquids A and B form a minimum boiling azeotrope at some specific composition, then _______________.
If two liquids A and B form a minimum boiling azeotrope at some specific composition, then _______________.
Minimum boiling azeotropes are those which boil at a temperature lower than the boiling points of each component in their pure state.
Minimum boiling point azeotropes are non-ideal binary solutions that show positive deviation from Raoult’s law.
Analysing the given options
\((A)\):
\(A-B\) interactions are stronger than \(A-A~\text{and}~B-B\) interactions. So, it shows negative deviation from Raoult’s law and forms a maximum boiling azeotrope.
\((B)\)
The vapour pressure of the solution increases due to weak \(A-B\) interactions in minimum boiling azeotropes. It is not due to the escaping of molecules.
\((C)\):
The vapour pressure of the solution increases and not decreases.
\((D)\):
Since minimum boiling point azeotropes show positive deviation, the \(A-B\) interactions are weaker than those between \(A-A~\text{or}~B-B\).
Hence, option (D) is correct.
