Question

Batch reactor with first order reaction. (+4 total) A researcher is attempting to produce ethanol using an enzyme catalyzed batch reactor. The ethanol is produced from corn starch by first-order kinetics with a rate constant of 0.05 hr1. Assuming the concentration of ethanol initially is 1 mg/L,what will be the concentration of ethanol (in mg/L) after 24 hours? Assume the reactor stays at a constant volume and temperature. How long will it take to reach a concentration of 10 mg/L ethanol?(Answer: C = 3.32 mg/L; t=46 hr).
