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.
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.
