Constant boiling mixtures are called

Azoetropes are constant boiling mixtures, which like a pure chemical compound boils at a constant temperature and distills over completely at same temperature without change in composition. There may be two type of binary solution which gives azeotropic mixture. Type-I: Mixture showing minimum in "Boiling point-Composition curve". Type-II: Mixture which showns a maximum in "Boiling point-Composition curve" Both types are shown below: For figure (I) and (II) predict which of the component(i.e., A and B) is more volatile?
