Question

what is a catalyst? Give 2 examples ​

Answer 1

Answer:

a catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

Example:

1.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.

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