f. A feed of a mixture of benzene (Bz) and toluene (Tol) is separated as shown in the figure below. Calculate the values of the distillate (D), the bottoms (B), the heat duty (heat removed by the water) in the condenser (Qc), and the heat duty (input) to the reboiler (QR). The recycle ratio R/D is 4.
