If biodegradable organic matter, oxygen, and microorganisms are placed in a closed bottle, the microorganisms will use the oxygen in the process of oxidizing the organic matter. the bottle may be treated as a batch reactor and the decay of oxygen may be treated as a firstorderreaction. write the general mass balance equation for the bottle. using a computerspread-sheet program, calculate and plot the concentration of oxygen each day for a periodof 5 days starting with a concentration of 8 mg/l. use a rate constant of 0.35 d-1
