i need mainly part c. please work it out!

P4-5 A Set up a stoichiometric table for each of the following reactions and cxpress the concentration of each species in the reaction as a function of conversion, evaluating all constants ( e.g. ,). Next, assume the reaction follows an elementary rate law, and write the reaction rate solely, as a function of conversion, i.c., rA=f(X). (a) For the liquid-phase reaction the entering concentrations of ethylene oxide and water, after mixing the inlet streams, are 16.13 mol/dm3 and 55.5mol/dm3, respectively. The specific reaction rate is k=0.1dm3/mol. s at 300K with E=12,500cal/mol. (1) After finding rA=f(X), calculate the CSTR space-time, , for 90% conversion at 300K and also at 350K. (2) If the volumetric flow rate is 200 liters per second, what are the corresponding reactor volumes? (Ans.: At 300K:V=439dm3 and at 350K:V=22dm3 ) (b) For the isothermal, isobaric gas-phase pyrolysis C2H6C2H4+H2 pure ethane enters a flow reactor at 6atm and 1100K. Set up a stoichiometric table and then write rA=f(X). How would your equation for the concentration and reaction rate, i.e., rA=f(X), ctynge if the reaction were to be carried out in a constant-volume batch reactor? (c) For the isothermal, isobaric, catalytic gas-phase oxidation the feed enters a PBR at 6 atm and 260C, and is a stoichiometric mixture of only oxygen and ethylene. Set up a stoichiometric table and then write rA as a function of partial pressures. Express the partial pressures and rA as a function of conversion for (1) a fluidized batch reactor and (2) a PBR. Finally, write rA solely as a function of the rate constant and conversion
