Please help. P10-1 b

The hydrodimethylation of toluene is to be carried out in a PBR catalytic reactor. C.HCH3 + H2 catalyst C.H. + CH, The molar feed rate of toluene to the reactor is 50 mol/min, and the reactor inlet is at 40 atm and 640C. The feed consists of 30% toluene, 45% hydrogen, and 25% inerts. Hydrogen is used in excess to help prevent coking. The pressure-drop parameter, a. is 9.8 x 10-5 kg! P10-18 (a) Example 10-1. Plot and analyze (1) the ratio of toluene-occupied sites to benzene-occupied sites, (2) the fraction of vacant sites, and (3) the fraction of benzene-occupied sites as a function of con- version at 1 atm. (b) Example 10-2. (1) What if the entering pressure were increased to 80 atm or reduced 1 atm, how would your answers change? (2) What if the molar flow rate were reduced by 50%, how would X and y change? (3) What catalyst weight would be required for 60% conversion
