A substrate is decomposed in the presence of an enzyme according to the Michaelis-Menten equation with the following kinetic parameters: Km 24 g/L Vmax - 12 g/L-min a. Determine the concentration of substrate leaving the second reactor in a two-reactor series of 20-liter CSTRs. The flow rate is 3.60 L/min. The inlet substrate concentration is 72 g/L. The enzyme concentration in the two reactors is maintained at the same value all of the time. b. Determine the efficiency in terms of substrate conversion of the two-reactor system and the efficiency of a single CSTR equal to the total volume of the two-reactor system. Clearly indicate the configuration with the greater efficiency.

Question
Transcribed Image Text:A substrate is decomposed in the presence of an enzyme according to the
Michaelis-Menten equation with the following kinetic parameters:
Km 24 g/L
Vmax - 12 g/L-min
a. Determine the concentration of substrate leaving the second reactor in a two-reactor series of
20-liter CSTRs. The flow rate is 3.60 L/min. The inlet substrate concentration is 72 g/L. The
enzyme concentration in the two reactors is maintained at the same value all of the time.
b. Determine the efficiency in terms of substrate conversion of the two-reactor system and the
efficiency of a single CSTR equal to the total volume of the two-reactor system. Clearly indicate
the configuration with the greater efficiency.
