c (Multiple reactions with heat effects) Xylene has three major isomers, m-xylene, o-xylene, and p-xylene. When o-xylene is passed over a Cryotite catalyst, the following elementary reactions are observed. The reaction to form p-xylene is irreversible: CH3 elon boa k1 CH3 k2 CH3 CH3 ot odT Mom 0L -CH3 CH3 The feed to the reactor is equal molar in both m-xylene and o-xylene (species A and B respectively). For a total feed rate of 2 mol/min and the reaction conditions below, plot the temperature and the molar flow rates of each spe- cies as a function of catalyst weight up to a weight of 100 kg. (a) Find the lowest concentration of o-xylene achieved in the reactor. (b) Find the highest concentration of m-xylene achieved in the reactor. (c) Find the maximum concentration of o-xylene in the reactor. (d) Repeat parts (a) to (c) for a pure feed of o-xylene. (e) Vary some of the system parameters and describe what you learn. (f) What do you believe to be the point of this problem? Additional informations All heat capacities are virtually the same at 100 J/mol K.
