= = Problem 1 (100 points): A liquid bioreaction A B +C has a reaction rate determined by the following equation: Fra = kC(1 + 2X 3X2) where X is the conversion of A, k = 0.05 L/mol/h, and the units for ra and CA are mol/L/h and mol/L, respectively. 1) (50 points) If the reaction is taken place in a single CSTR, the volume flow rate for both inlet and outlet flow vo = v= - 0.5 L/h, the concentration of A in the entrance is CA0 = 3 mol/L and no B is in the entrance, please determine the volume required for the CSTR to achieve a conversion X1 = 1/3. 2) (50 points) If a second flow reactor (either CSTR or PFR) is added and connected with the first CSTR in series to achieve a conversion X2 = 2/3, should the second reactor be CSTR or PFR so that its volume is smaller? Please explain your choice. Hint: please note X This function has a maximum value at X= 1/3. You may use the Levenspiel Plot to explain your choice without the need of directly calculating and comparing the volumes of both CSTR and PFR. - 4 = C (1 + 2x - 3x) = 3kC (-(x-2) = 3
