Example 05.05 Temperature Dependence of the Activity Coefficients
Estimate the activity coefficients for the system ethanol (1) - water (2) at theta = 50 °C using the experimental excess enthalpy data of Larkin assuming that the excess enthalpy is independent of temperature.
Liquid and vapor mole fractions, temperature, pressure
Activity coefficients at theta = 70°C
Partial molar excess enthalpies:
Calculation of the activity coefficients at theta = °C
