Hydrogen peroxide decomposes to water and oxygen, and the activation energy for this process is 42 kJ/mol. The hydrogen peroxide formed in the biological process is harmful to tissue, but the enzyme catalase catalyzes the decomposition of hydrogen peroxide by lowering the activation energy to 7.0 kJ/mol. Assuming the frequency factor is the same for both processes and independent of temperature, calculate the temperature required for the uncatalyzed decompostion to proceed at the same rate as the enzyme-catalyzed decomposition at 37 degrees Celcius (normal body temperature). Is this a reasonable temperature for a biological organism?
