what is catalyst give an example
Answers
In chemistry, a catalyst is a substance that causes a chemical reaction to happen in a different way than it would happen without that catalyst - for example, a catalyst could cause a reaction to happen at a faster rate, or at a lower temperature, than would be possible without the catalyst.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.
The catalytic converter in a car contains platinum, which serves as a catalyst to change carbon monoxide, which is toxic, into carbon dioxide.
If you light a match in a room with hydrogen gas and oxygen gas, there will be an explosion and most of the hydrogen and oxygen will combine to create water molecules.
Catalyst are the substances which are used in the chemical reactions because they increases rate of reaction without being used in it
