1 (25 points) Consider a simple reactor in which a highly concentrated hydrogen peroxide (H2O2) solution is fed to an aqueous waste containing a non-volatile and biologically resistant organic compound. The concentrated H2O2 solution is used to partially oxidize the organic compound in the wastewater prior to its discharge to a biological treatment process. The wastewater is introduced at one end of the tank and withdrawn at the other at a flow rate of Q. The flow rate is considered constant (i.e., change due to the hydrogen peroxide is insignificant). The contents of the tank are also kept completely mixed by a mechanical mixer. (a) (10 points) Draw a simple schematic of the reactor. Based on the schematic, write an unsteady-state material balance for the original organic compound in the system. Assume that the rate of oxidation of the organic compound is directly proportional to its concentration (i.e., first-order decay). State clearly all your assumptions and provide initial conditions for the problem. Use the symbols provided in the problem and define any new ones you introduce in your equations
