An organic compound MO dispersed in wasterwater is catalytically to MO2 using an enzyme (total enzyme concentration = Ea). The enzyme is uniformly disperesed in water. Waste water contains dissolved oxygen which also participates in aqueous phase oxidation of dispersed organic compound. Determine the rate of the enzymes reaction based on the following four-step reaction mechanism. MO + E = MOE (Very fast and reversible ) O2 + E = O2E (Very fast and reversible) MOE + O2E = (Very slow reaction and irreversible) MOE + MO3E = 2MO2 + 2E(Very slow reaction and irreversible)
