Catalase is an enzyme that promotes the conversion of hydrogen peroxide (H 2 O 2 ) into
Question:
Catalase is an enzyme that promotes the conversion of hydrogen peroxide (H2O2) into water and oxygen. The diffusion constant and radius for catalase are 6.0 × 10–7 cm2 s–1 and 51.2 Å, respectively. For hydrogen peroxide the corresponding values are 1.5 × 10–5 cm2 s–1 and r ∼ 2.0 Å. The experimentally determined rate constant for the conversion of hydrogen peroxide by catalase is 5.0 × 106 M–1 s–1. Is this a diffusion-controlled reaction?
Step by Step Answer:
Using the information provided the diffusioncontrolled rate constant can be ...View the full answer

Hydrogen peroxide can be used as a mild antiseptic to curb superficial skin infections such as athlete’s foot, but only in diluted quantities. To combat stinky feet, try soaking your feet in a solution of 1 part 3% hydrogen peroxide and 3 parts warm water for 15-20 minutes, then drying them thoroughly. This will kill odor-causing bacteria and soften your feet. To treat athlete\'s foot, you can use a similar solution, but only in diluted quantities, and soak your feet for 30 minutes. Hydrogen peroxide can also be used to keep vegetables fresh by adding 1/4 cup to a bowl of cold water, soaking the vegetables for 20-30 minutes, then draining, drying, and refrigerating them. Alternatively, you can spray vegetables with a solution of 3% hydrogen peroxide and let them stand for a few minutes before rinsing and drying. To keep leftover salad fresh, spray it with a solution of 1/2 cup water and 1 Tbsp. 3% hydrogen peroxide, drain, cover, and refrigerate.
