Question: Describe the phase changes that take place when a liquid mixture of 4.0 mol B2H6 (melting point 131 K) and 1.0 mol CH30CH3 (melting point

Describe the phase changes that take place when a liquid mixture of 4.0 mol B2H6 (melting point 131 K) and 1.0 mol CH30CH3 (melting point 135 K) is cooled from 140 K to 90 K. These substances form a compound (CH3), OB2H6 that melts congruently at 133 K. The system exhibits one eutectic at x (B2H6) = 0.25 and 123 K and another at x(B2H6) = 0.90 and 104 K.
