ChE 131 Solutions Thermodynamics 1. Refer to class lecture notes, showing the characteristic plots of the composition dependence of GE,HE, and TSE for the real binary mixture ethanol (1) / n-heptane (2) at 50C,1atm. Do your own calculations to come up with equivalent plots. You are free to choose your models for this system.
