Phase Equilibrium: Fugacity and Equilibrium Calculations
 Relate the fugacity and the chemical potential (or the partial
molar Gibbs free energy)
 Use the fugacity coefficient to calculate the vapor phase
fugacity
 Use the activity coefficient to calculate the liquid (or solid)
phase fugacity
 Identify conditions when a liquid or solid mixture would form
an ideal solution
 Explain when LewisRandall versus Henry ideal solution
reference states are appropriate
 Use the GibbsDuhem equation to relate activity coefficients in
a mixture
 Perform bubblepoint and dew point calculations

 using Raoult's Law
 using complete fugacity relations (assuming known fugacity
coefficients and activity coefficients)
 Draw and read Txy and Pxy diagrams for VLE
 Use Henry's Law to calculate VLE for gases dissolved in
liquids
