catalysts

Definition of a catalyst

Increases the rate of chemical reactions but are not used up during the reaction

What do catalysts allow us to do

Carry out reactions quickly without needing to increase the temperature, saving money

Bonus of catalysts

Since they are not used up during reaction, we can reuse them again and again

How do catalysts increase the rate of reaftion

By providing different pathway for the reaction that has a lower activation energy

What is the case when a catalyst is present

The particles require less energy to cross the activation energy barrier, meaning more particles can successfully collide per second

What do we not include catalysts in

Chemical equations for reaftion, since they are not used up and aren’t a reactant

Different reactions need…

Different catalysts

What are catalysts in living organisms

Enzymes
