Dependence between the Liquid and Gas Concentrations in Equilibrium State of Ethanol-Water Mixtures at 50 °C

This example explains, how you can use the empirical equations for activity coefficients in the calculations. 
Liquid-gas-concentration- (x-y-diagram), enthalpy-concentration-diagrams, activity coefficients in dependence on the concentrations are calculated and plotted..
