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., = = =). Next, assume the reaction follows an elementary rate law, and write the reaction rate solely as a function of conversion, that is, -ra = f(x). a. For the liquid-phase reaction CH2-OH H2SO4 CH2-CH2+H20 CH2-OH the entering concentrations of ethylene oxide and water, after mixing the inlet streams, are 16.13 and 55.5 mol/dm>, respectively. The specific reaction rate is k = 0.1 dm/mol -s at 300 K with E = 12500 cal/mol. 1. After finding - A = 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 dm and at 350 K: V = 22 dm) b. For the isothermal gas-phase pyrolysis CH - CH = H2 pure ethane enters a flow reactor at 6 atm and 1100 K, with AP = 0. Set up a stoichiometric table and then write --A = f(x). How would your equation for the concentration and reaction rate, that is, --A = f(x), change if the reaction were to be carried out in a constant-volume batch reactor? c. For the isothermal, isobaric, catalytic gas-phase oxidation C2H4+02 CH-CH2 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 r as a function of partial pressures. Express the partial pressures and r as a function of conversion for (1) a fluidized batch reactor and (2) a PBR. Finally, write r solely as a function of the rate constant and conversion
