Apply the lever rule to a two-phase region of a P-x-y or T-x-y diagram. 12. Apply Henry’s law relations to calculate amounts dissolved in liquid phases. 13. Calculate liquid phase fugacities for non-ideal solutions 14. Explain the assumptions in Raoult’s low. 15. Calculate equilibrium compositions and/or equilibrium pressures for ideal solutions and ideal gases (Raoult’s law). 16. Calculate bubble points and dew points (both temperature and pressure) using Raoult’s law. 17. Apply Raoult’s law to flash calculations. 18. Calculate fugacities of each component in an ideal gas mixture. 19. Calculate for an ideal solution, the enthalpy of mixing, the entropy of mixing, the volume of mixing, and the Gibbs free energy of mixing. 20. Predict which mixtures can be treated as ideal solutions....
