Question

Explain with one example 'The rate of chemical reaction increases due to catalyst'

Please help me fast I need it quick​

Answer 1

The rate of a chemical reaction increases due to a catalyst because catalyst lower the activation energy of a reaction.

A catalyst can be described as an element or molecule which increases the speed of a chemical reaction by lowering its activation energy.

A catalyst itself remains unchanged in the chemical reaction.

For example, two molecules of hydrogen peroxide react to decompose into water and oxygen. This decomposition reaction occurs faster when the catalyst potassium permanganate is used.
