1
Q
What do catalysts do?
A
Change the rate of chemical reactions but are not used up or changed during the reaction
2
Q
What do different reactions need?
A
Different catalysts
3
Q
What are enzymes?
A
Catalysts in biological systems
4
Q
How do catalysts increase the rate of reaction?
A
By providing a different pathway for the reaction that has a lower activation energy
