1

What happens to catalysts after they catalyse a reaction?

Nothing, they can be used up again and again as they are not affected in the reaction

2

What adaption do solid catalysts have?

Large surface area to make them as effective as possible

3

Why do different reactions need different catalysts?

Catalysts often only work with one type of reaction

4

How do catalysts work?

They speed up the rate of reaction by lowering the activation energy so more of the collisions result in a reaction
