Open in App
Solution
The correct option is B High boiling azeotrope
Volume of A=100 ml ; Volume of B=50 ml.
Ideal solution =100+50=150 ml
Non ideal =138 ml
ΔVmix=138−150=−12<0
This condition occurs when the vapour pressure of the solution is lesser then it should be.Since the vapour pressure of the solution is lesser, therefore, the solution boils at a higher temperature.
Hence, option B is correct.
