Rate Determining Step and Catalysts
High schoolers investigate the rate determining step in a chemical reaction and how catalysts effect reactions. In this rate determining step and catalyst lesson, students work in groups to perform 5 tasks. They rotate each task and time how long the tasks take to complete. They compare their answer and conclude the rate determining step (the slowest step). High schoolers use liver blood and hydrogen peroxide to observe the rate determining step of the breakdown of hydrogen peroxide.
