Incorrect Question 7 0/0.5 pts What are the eutectic properties for the the binary liquid-solid phase diagram of the naphthalene-diphenylamine system? The eutectic termperature is the highest melting point. The eutectic temperature depends on the molar fraction of naphtalene. The eutectic temperature never changes. The eutectic composition depends on pressure. The eutectic termperature depends on pressure. The eutectic composition never changes. The eutectic composition depends on the molar fraction of naphtalene.
