I need detailed help solving this exercise from homework of Engineering Mathematics II.I do not really understand how to do, please do it step by step, not that long but clear. Thank you!P.S.: Please do not use AI, thanks!
PGE508 Assignment 2 A mixture with 4% n-pentane, 40% n-hexane, 50% n-heptane, and 6% n-octane is to be distilled at 14.7 lb/in² (1 atm.) with 98% of the hexane and 1% of the heptane recovered in the distillate. If the liquid feed is a saturated liquid (i.e., q = 1). Calculate i.) The product compositions, ii.) The top and bottom temperature iii.) Minimum reflux ratio (Rm), iv.) Minimum theoretical plates and v.) Actual plates when the reflux ratio is 2Rm. Table 1: Component boiling point and molar mass Component Boiling point n-C 97°F n-C 156.2°F n-C 209.1°F n-Cs 258.1°F Molar mass 72.2 86.2 100.2 114.2 Hint: Since 1% of heptane is specified to be recovered in the distillate, 99% of heptane is to be recovered in the bottom.
