Question

3. (15 points): The reaction of is carried out isothermally in a continuous flow reactor. Calculate both the CSTR and the PFR reactor volumes (if it is possible) necessary to consume 96% of S (ie. S-0.04*So) when the entering volumetric flow rate is at a constant 12 L/hr. Assume the reaction rate -rs follows normal Michaelis-Menten kinetics (the product formation step is slow and rate limiting) where the substrate binds with the enzyme to form complex ES. Assume that there is no immobilization or inhibition effects present. a. S.-1.5 mol/L and Vinas-4.50 mol (hr* L) and Km = 0.0300 mol/L b. So 0.030 mol/L and Vmax-0.10 mol/(hr L) and Km-0.095 mol/L c. S,-0.90 mol/L and Vimax = 0.10 mol/(hr*L) and Km = 0.0750 mol/L If it is not possible to determine the reactor volumes for the data given above, list the remaining variables that are needed to determine the reactor volumes.
