Create the T-xy diagram: Using vapor pressure data from Appendix B.4, prepare a complete T-xy diagram for the binary system ethylbenzene and o-xylene at a system pressure of 0.8 atm. Be sure to show sufficient detail of your calculations (by hand, in an EXCEL spreadsheet, or in PolyMath). Your T-xy diagram should have mole fractions of the more volatile component on the x-axis. Roughly estimate how many equilibrium stages would be required in a distillation tower to achieve a distillate of 90% ethylbenzene, if one started with a feed mixture of 40% ethylbenzene / 60% o-xylene
