Catalysts

Question 1

Catalysts are a substance that?

Answer 1

substances that speed up a reaction without being consumed in the process

Question 2

Are catalysts reactants or products?

Answer 2

BOTH.

Question 3

Catalysts are typically?

Answer 3

proteins (but not always)

Question 4

Catalysts speed up a reaction by?

Answer 4

Lowering the reactions activation energy by creating an alternate path for the reaction. It does NOT change the energy levels of the reactants or products

Question 5

Catalysts lower a reaction’s activation energy by providing?

Answer 5

By providing an alternate pathway (different reaction mechanism) between reactants and products

Question 6

Do catalysts shift equilibrium reactions?

Answer 6

NO! No! no! They only help a reaction reach equilibrium quicker.

Question 7

Can catalysts change the energy levels of reactants and products?

Answer 7

NO

Question 8

What are two major things catalyst do NOT do?

Answer 8

1) change the reactants or products energy levels in a reaction
2) shift equilibrium by being added or removed
