The enzyme catalase effectively decomposes hydrogen peroxide

and the kinetics of this reaction are to be evaluated from an experiment in which dilute H202 flows through a packed bed of kieselguhr particles impregnated with immobilized enzyme. From the following data, reported by Krishnaswamy and Kitterell, AZChE J., 28, 273 (1982), develop rate expressions to represent this decomposition, both in the diffusion free regime and in the strong pore diffusion regime, for the catalyst at hand. Note that the conversion decreases with time in all runs showing that the catalyst deactivates with use.
