    (a) Neglect pressure drop and determine the activity and concentration profiles as a function of catalyst weight along the reactor.
(b) Repeat part (a) by accounting for pressure drop for the case where the gas density varies down the reactor [i.e.image 10eq16a.gif. Both reactants and fresh catalyst enter at the same end.
