please make your writing easy to read, and make the picture clear. there is a solution of this queation on chegg, please dont copy because its not clear for me

Q1) A feed mixture contains four components Benzene, Toluene, Xylene and Cumene. The feed rate is 200kmol/h. The feed is at the bubbling point at 113C and an atmospheric pressure. It is required to design the distillation column so that recovery ratio of cumene in the bottom is 99.8% and the recovery ratio of toluene in the distillate is 99.5%. Assume no benzene in the bottom product and no xylene in the top product. Assume vapor is ideal gas and the liquid density is 865kg/m3 and surface tension is 10 dyne/cm, 80% flooding and 15% down comer area. Tray spacing is 24 in. Assume liquid and vapor molecular weight is the same. Assume R/Rmin=1.2 Estimate a) Distillate and bottom flow rates and compositions b) Reflux ratio c) Number of trays d) Feed location e) Tray diameter, ft (40pts) Hint: use Antoine Equation to find vapor pressure values
