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 First-order Reaction1.Write the general Mass Balance Equation for the botlle and the Integrated Form of this equation for this problem. 2.Calulate and plot the Concentration of Oxygen remaining at the end of each day for a period of Five Days if the concentration at the beginning of the experiment (time=zero) is 8.0 mg/L and K=0.35 Days-1
