A A 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., , 0). Next, assume the reaction follows an elementary rate law, and write the reaction rate solely as a function of conver- sion, i.e., -r = f(x). (a) For the liquid-phase reaction CH2-OH | H2SO4 CH2-CH+H2O CH,OH the entering concentrations of ethylene oxide and water, after mixing the inlet streams, are 16.13 mol/dmz 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 -r = 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 vol- umes? (Ans.: At 300 K: V = 439 dmz and at 350 K: V = 22 dm3) A
