In Activity: First-order Rate Constant from Graph, in today’s work, data are given for the decomposition of hydrogen peroxide. Hydrogen peroxide decomposes to form oxygen and water. Write a balanced chemical equation for decomposition of hydrogen peroxide. How is the equation you wrote for hydrogen peroxide different from the chemical equation A → products that was used to derive the integrated rate law?
Now define the rate of reaction for decomposition of hydrogen peroxide using the method given earlier and derive the integrated first-order rate law, following the derivation outlined today. Use your mathematical work to show that the rate constant calculated in Activity: First-order Rate Constant from Graph for the first-order decomposition of hydrogen peroxide is twice as big as it should be.
Two days before the next whole-class session, this Podia question will become live on Podia, where you can submit your answer.
