Step 1

Part (a)

Let the reaction taking place in the CSTR be,

 

S→P

 

According to the Michaelis-Menten equation, the reaction rate for this reaction is defined as written below.

Step 2

For two CSTR’s in series;

Volume of each CSTR is, V = 20 L

Volumetric flowrate is, V̇ = 3.60 L/min

Initial concentration of the substrate is, [S0] = 72 g/L
