(a) Develop a rate law, and evaluate all the rate law parameters.
(b) Suggest a mechanism consistent with the experimental data Hydrogen and i-octene are to be fed in stoichiometric proportions at a total rate of 5 mol/min at 200ºC and 3 atm.
(c) Neglecting pressure drop, calculate the catalyst weight necessary to achieve 80% conversion of i-octene in a CSTR and in a plug-flow reactor.
(d) If pressure drop is taken into account and the -in. catalyst pellets are packed in -in. schedule 80 pipes 35 ft long, what catalyst weight is necessary to achieve 80% conversion? The void fraction is 40% and the density of the catalyst is 2.6 g/cm3
