Problem 1:
1. The following sequences of reactions are to occur in a constant density reactor. Which type of continues flow-reactor would be best to maximize the selectivity for product C?
a. A + B → C rc = kI CA3/12CB
A + B → D rD = k2CACB3/2
b. For the set of reactions in part (a) kI = 1.25 L/mol.min and k2 = 0.53 L/mol.mn. If a feed of 2.4 mol/L of A and 1.2 mol/L of Bare fed to the selected reactor in (a)
i. What volume of rector is needed to achieve 45% conversion of A? The volumetric flow rate v0 is 10 L/min.
ii. Plot the concentration of A, B, C and D as a function of space time (r), what is the overall yield of C at 45% conversion of A?
