For the binary n-hexane/n-octane system, prepare t-x-y and y-x phase equilibrium graphs at 202 kpa. use excel for the calculations and submit the two graphs on one page in landscape orientation. use the actual value of yl as computed by a bubble temperature calculation. b. 5 pts. submit another page showing the spreadsheet of calculations used to prepare the graphs in part a. these should be similar to those uploaded for lecture #3 for the methanol-water system. be sure to include a line showing sp#8 for che 305 hw # 2 and your name on the spreadsheet. be sure to calculate the ki, k2, and a12. it is not necessary to have the table showing the guessed values. that is, it is sufficient to show the temperature corresponding to the ey,-1.0-0 obtained by using goal seek or solver.
