Rectification of a Heptane$-$Ethyl Benzene Mixture. A saturated liquid feed of $200mo\frac{l}{h}$ at the boiling point containing $42$mol$\%$ heptane and $58\%$ ethyl benzene is to be fractionated at $101\mathrm{.}32$kPa abs to give a distillate containing $97$mol$\%$ heptane and a bottoms containing $1\mathrm{.}1$mol$\%$ heptane. The reflux ratio used is $2\mathrm{.}5$:$1.$ Calculate the $mo\frac{l}{h}$ distillate, $mo\frac{l}{h}$ bottoms, theoretical number of trays, and the feed tray number. Equilibrium data are given below at $101\mathrm{.}32$kPa abs pressure for the mole fraction $n-$heptane $x_H$ and $y_H.$
