2. Enzymatic reactions. Beef catalase has been used to accelerate the decomposition of hydrogen peroxide to yield water and oxygen [Chem. Eng. Educ., 5, 141 (1971)] in a batch reactor. The concentration of hydrogen peroxide is given as a function of time for a reaction mixture with a pH of 6.76 maintained at 30°C. t (min) 0 10 20 50 100 CH2O2 (mol/L) 0.02 0.01775 0.0158 0.0106 0.005 a. Determine the Michaelis-Menten parameters. b. If the total enzyme concentration is tripled, what will the substrate concentration be after 20 minutes?
