4. Now consider the catalase catalyzed decomposition of hydrogen peroxide to water. The much needed catalyst. 2H202 + catalase → 2H2O + O2 + catalase a. [3] Assume the following mechanism: H2O2 + catalase = {H202-catalase} HIS 54 Inhibitor ASN 127 H2O2 + {H202-catalase} → catalase + 2H20 + O2 Oxygen When the pre-equilibrium approximation is used, the rate-law is: 41 dt Kegk2[H202]?[E]. The steady-state approximation gives a more general rate law. Derive the rate law using the SS approximation....
