Benzene (A) melts at 6 0C and diphenylmethanol (B) melts at 65 0C. The solids are mutually immiscible. There is a eutectic at 1 0C, the eutectic solution being 20 mol % in B, and an unstable compound, AB2, which decomposes at 30 0C. Depict and label the simplest melting point diagram consistent with the preceding information. Outline with reasonable attention to detail the cooling curves for solutions containing 10% B and 67% B.
