For mixtures of (1) 1-propanol with (2) water, the Wilson parameters are as follows: 912- 75.48. mol 921- 1351.9.cal mol Molar volumes for the two molecules are as follows: V₁-75.14² mal V₂ - 18.07m² mol Estimate the bubble point temperature in Kelvin and vapor phase concentration of 1-propanol if the pressure is 101.33 kPa and the liquid phase concentration of 1-propanol is 30 mol%. Estimate the dew point temperature and the liquid phase concentration of 1-propanol if the pressure is 101.33 kPa and the vapor phase concentration of 1-propanol is 30 mol %. A mixture with an overall composition of 30 mol % 1-propanol is fed to a flash tank held at 101.33 kPa and Temp = (Tdew+Toubble). Estimate the liquid and vapor phase concentrations of 1-propanol and the percent that is recovered as vapor. Determine the temperature in Kelvin and the concentration of 1-propanol at the azeotrope when pressure is maintained at 101.33 kPa.

Sea water at 20ºC and 1 bar. If the salt mole fraction in the water is 0.01, what is the entropy of H2O in the sea water? Note: the question can be analyzed by the ideal solution, and it is as follows: Si=niSmi0-niRlnx
