When the temperature increases from 30℃ to 37℃, the rate of an enzyme-catalysed reaction increases by a factor of 1.47. Calculate to 3 significant figures the activation energy for this reaction.
A sample of hydrogen peroxide decomposes with a rate constant of s−1 at 80℃ and s−1 at 35℃. Calculate to 3 significant figures the activation energy for this reaction.
Butene can decompose to two molecules of ethene when heated. The rate constant for the decomposition reaction at 325℃ is s−1 and the activation energy is 261.0 kJ/mol. Estimate the frequency (pre-exponential) factor for the reaction, to 2 significant figures.
