You are interested in modeling the SLE phase behavior for the hexane-1, 6 diamine (1) + naphthalene system by assuming an ideal solution for the liquid phase, but treating the solid phases as immiscible.

(a) Produce a plot of the SLE for this system. 

(b) At what temperature and composition does the eutectic occur? 

(c)  If you cool a liquid system of 60% hexane-1, 6 diamine from 330 K to 300 K, describe the equilibrium phases as the temperature is lowered
