Question

hy guys ..pleasese help mewhat is catalist....​

Answer 1

A catalyst is a substance that enables a chemical reaction to accelerate at a usually faster rate.

In other words,

They speed up reactions that are otherwise very slow.

There are 3 types of catalysts.

• Homogeneous catalysts

• Heterogeneous catalysts

• Biocatalysts

Catalysts work by lowering the amount of energy required for the reaction to take place.

• Example - Enzymes act as catalysts in the human body
• Many proteins in the body act as catalysts that help in various different functions in the body.

In a reaction where catalysts are used, a lower activation energy route is taken than the actual reaction route.

                                                                       

Answer 2

Answer:

Definition of catalyst

1 : a substance that enables a chemical reaction to proceed at a usually faster rate or under different conditions (as at a lower temperature) than otherwise possible

2 : an agent that provokes or speeds significant change or action
