Unformatted text preview: containing N species? 3) (25 points) A binary mixture has the following relationship for its excess enthalpy: H E = 20 x A x B [kJ/mol] a. Calculate and graph the free energy of mixing, G, as a function of x A at 800K, 1000K, and 1500K. b. For an equimolar mixture of these species, determine the number of phases and the composition of each phase at 800K, 1000K, and 1500K. 4) (25 points) A binary liquid system exhibits LLE at 25 o C. For x 1 = 0.10 and x 1 = 0.90, determine estimates for parameters A 12 and A 21 in the Margules equation at 25 o C....
