Description

One way to lower the energy barrier of a chemical reaction and consequently overcome it more quickly is to add a catalyst. In the following experiment the students learn about such a catalytic reaction. They will compare the reaction rate of the decomposition reaction of hydrogen peroxide with and without the catalyst manganese dioxide as well as when the solution is heated.
