The substances which have potential to make chemical reactions even more faster are called catalysts .By using these , in case of need , chemical reactions can be made more effective i.e .; by reaction taking place in faster rate and at lower temperature etc...
Example: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 vapour will shoot out.
