試題詳解

26. The vapor pressure of a binary liquid mixture that is composed of hydrazine (b.p. 114 °C) and water (b.p. 100.0 °C) exhibits a negative deviation from Raoult's law. Then we know that
(A) the mixture on fractional distillation yields a low-boiling azeotrope.
(B) the mixture on fractional distillation yields a high-boiling azeotrope.
(C) the boiling point of the mixture is always between 100 and 114 °C.
(D) the boiling point of the mixture may be higher than 114 °C.
(E) the boiling point of the mixture may be lower than 100 °C
