1. Smith, van Ness & Abbott, problem 11.1
2. Smith, van Ness & Abbott, problem 11.3
3. Smith, van Ness & Abbott, problem 11.6
4. Smith, van Ness & Abbott, problem 11.9
5. Obtain from the literature experimental vapor-liquid equilibrium data for the binary mixture n-propanol - water at 1.01 bar.  Plot the data as temperature versus composition of the liquid and vapor phases.  On the same plot, compute the corresponding curves obtained using the van Laar model for the activity coefficients, with A = 2.60 and B = 1.13 (assumed constant).  Use the Antoine equation for pure-species vapor pressures, and assume an ideal vapor.  Try this reference for the experimental data, if you wish:  P.S. Murti and M. van Winkle, Chem. Eng. Data Ser. 3, 72 (1958).
