A completely mixed chemical reactor has an nfluent flow with a concentration of 150 mg/l of A and a flowrate of 100 gal min (380 l/min). The eaction is first order, the rate equation is dC dt = KC = -TA and the rate constant is 0.40 hr. Determine:

a)

The required detention time and the volume of he reactor if the effluent contains 20 mg/l of A.

Express volume as gallons and liters.

b) A plot of percent C removed or converted ersus detention time.

c) How many times larger a completely mixed re- ctor must be than a plug-flow reactor for 80%. emoval or conversion.

d) How many times larger a completely mixed re- ctor must be than a plug-flow reactor for 90, emoval or conversion.

3.4 A completely mixed chemical reactor has an nfluent flow with a concentration of 150mg/ of 1 and a flowrate of 100 gal-min (380l/min). The eaction is first order. the rate equation is dtdCA=kCA=rA ind the rate constant is 0.40hr1. Jetermine: 2.
