A specific enzyme acts as catalyst in the fermentation of reactant A. At a given enzyme concentration in the aqueous feed stream (25 liter/min) find the volume of the plug flow reactor needed for 95% conversion of reactant A (C_A0
=2 mol/liter). The kinetics of the fementation at this enzyme concentration is given by

A----------> R     -r_A=[0.1C_A/(1+0.5C_A)] mol/liter.min
