PROBLEM #1 (40 points) Ethanol is now at the core of the energy economy. Given a binary mixture system of ethanol(!)/water(2) at 80 degC. We need to conduct an analysis of phase equilibrium of the system by answering the following questions. a) (20 points) Given that the excess Gibbs energy for the ethanol(1)/water(2) system at 80 degC is well represented by (A2111 + A12X2)X112 GE RT and activity coefficents at infinite dilutions (from two-parameter Margules equations) are nie = 1.732 & Y = 1.964 determine the activity coefficients 71 & 72 given that the liquid phase contains 60 mole percent ethanol and 40 mole percent water. b) (5 points) What is the value of GE?
