2500 kg/hr of a mixture containing equal parts by mass of benzene and toluene are distilled. The flow rate of the overhead product stream is 988 kg/hr , and the bottom stream contains 17.03 wt% benzene. Draw and label a flowchart of the process. Then calculate the mass and mole fractions of benzene and the molar flow rates of benzene and toluene (mol/hr) in the overhead product stream.
