PROBLEM #1 (40 points) Ethanol is now at the core of the energy economy. Given a binary mixture system of ethanol(1)/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 GE RT (A2131 + A1272)232 and activity coefficents at infinite dilutions (from two-parameter Margules equations) are 7 = 1.732 & n = 1.964 determine the activity coefficients 7 & 72 given that the liquid phase contains 60 mo percent ethanol and 40 mole percent water. b) (5 points) What is the value of G?
