4. E.T. Hessen et al. report the P-r-y diagram for the binary system monoethanolamine (MEA) and water at 60 °C (See page 2 of this assignment). For a mixture in equilibrium at 60 °C where the composition of the liquid phase is IMEA = 0.7, find: (a) (20 points) The activity coefficients (7) for MEA and water. Use vapor pressures of pure compounds as reference fugacities (f). Since it is low pressure, you can assume ,= 1. (b) (5 points) The molar excess Gibbs energy (GE, J/mol) (c) (5 points) The single-parameter A in Margules equation. No need to regress all data, use the single point IMEA=0.7
