Question

For this one, I understand why it is not a PFR and not a semi-batch with B added to A. However, how do I know whether the semi-batch of A added to B versus the two CSTRs is better for selectivity? What if it was one CSTR?

3. If the following reactions are elementary, what would be an appropriate scheme for increasing
SD/U?
A+B → D
2A + BU
A. Semibatch reactor in which B is slowly added to a container of A
B. Semibatch reactor in which A is slowly added to a container of B
C. Series of two CSTRs with a 1:1 feed of A:B
D. Plug flow reactor
