P4-5 Set up a stoichiometric table for each of the following reactions and express the concentration of each species in the reaction as a function of conversion, evaluating all constants (e.g., e, 0). Next, assume the reaction follows an elementary rate law, and write the reaction rate solely as a function of conversion, i.e.,-/A = f(x). (a) For the liquid-phase reaction CH₂-OH H₂SO4 CH2-CH₂+ H₂O CH₂-OH the entering concentrations of ethylene oxide and water, after mixing the inlet streams, are 16.13 mol/dm³ and 55.5 mol/dm³, respectively. The specific reaction rate is k = 0.1 dm³/mol.s at 300 K with E 12,500 cal/mol. (1) After finding - = f(x), calculate the CSTR space-time, t, for 90% conversion at 300 K and also at 350 K. (2) If the volumetric flow rate is 200 liters per second, what are the corresponding reactor volumes? (Ans.: At 300 K: V = 439 dm³ and at 350 K: V = 22 dm³) (c) For the isothermal, isobaric, catalytic gas-phase oxidation CH+O, CH2-CH₂ the feed enters a PBR at 6 atm and 260°C, and is a stoichiometric mixture of only oxygen and eth- ylene. Set up a stoichiometric table and then write - as a function of partial pressures. Express the partial pressures and as a function of conversion for (1) a fluidized batch reactor and (2) a PBR. Finally, write - solely as a function of the rate constant and conversion.
