One of the ways that benzene is produced on a large scale is the hydrodealkylation of toluene. C6H5CH3+H2C6H6+CH4 A stream of toluene is mixed with a recycle stream and enters a reactor along with a stream of pure hydrogen. The reaction products at 540C enter a condenser, where they are cooled to 43.0C. A vapor stream containing ySCH4=0.580molCH4/mol leaves the process, and a liquid stream containing x6b=0.660mol benzene /mol and x6t=0.340mol toluene/mol enters a distillation column. The distillate of the column leaves the process at n7=728.0mol/h and contains y7b=0.9400mol benzene /mol and y7t=0.0600mol toluene/mol. The bottoms of the column contains x8b=0.210mol benzene/mol and x8z=0.790mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at n1=1.350103molH/h. This process is carried out at 760mmHg. What are y5b and y5t, the mole fractions of benzene (b) and toluene (t), respectively, in the vapor stream leaving the condenser? y5b= mol b/mol What is n2, the flow rate of fresh toluene into the process? What is n8, the flow rate of the recycle stream
