Concept explainers
(a)
Interpretation:
Whether benzene and methanol show nearly ideal, positive or negative deviation is to be determined.
Concept introduction:
Azeotropes are the mixture of liquids that has a constant boiling point because the vapor has the same composition as that of the liquid mixture. The boiling points of such mixtures may be higher or lower than any of its components.
For components A and B, there will be a positive deviation if
(b)
Interpretation:
Whether water and ethyl acetate show nearly ideal, positive or negative deviation is to be determined.
Concept introduction:
Azeotropes are the mixture of liquids that has a constant boiling point because the vapor has the same composition as that of the liquid mixture. The boiling points of such mixtures may be higher or lower than any of its components.
For components A and B, there will be a positive deviation if
(c)
Interpretation:
Whether hexane and heptane show nearly ideal, positive or negative deviation is to be determined.
Concept introduction:
Azeotropes are the mixture of liquids that has a constant boiling point because the vapor has the same composition as that of the liquid mixture. The boiling points of such mixtures may be higher or lower than any of its components.
