(A) It shows a negative deviation.      
(B) It forms a maximum boiling azeotropic mixture.
(C) ΔS>0
(D) ΔG<0       
(E) Components can be separated by fractional distillation.


Solution

Negative deviation is seen as A-B interactions are stronger than A-A or B-B interactions. Due to this, a maximum boiling azeotropic mixture can be formed.

Entropy of mixing is always positive and Gibb's energy is negative as it is a spontaneous process.
