Can someone give an example of a catalytic reaction?

When hydrogen peroxide decomposes into water and oxygen gas, the process is quite slow. Adding the catalyst potassium permanganate will speed up the reaction, causing it to proceed almost instantly by using an alternate energy pathway that requires a lower activation energy.

Countless biological chemical reactions are also catalyzed by proteins, such as the metabolization of lactose using lactase.

Enzymes are examples of catalytic reactions, where one molecule that isn't used up helps to facilitate the reaction of another set of molecules.

The catalytic converter in a car contains platinum, which serves as a catalyst to change carbon monoxide, which is toxic, into carbon dioxide.

Hydrogen peroxide will decompose into water and oxygen gas. Two molecules of hydrogen peroxide will produce two molecules of water and one molecule of oxygen. A catalyst of potassium permanganate can be used to speed up this process. Adding potassium permanganate to the hydrogen peroxide will cause a reaction that produces a lot of heat, and water vapor will shoot out.
