Question

How does a catalyst work

Answer 1

Assuming you know what a catalyst is :

A catalyst works by providing a convenient surface for the reaction
to occur. The reacting particles gather on the catalyst surface and...

• collide more frequently with each other

• more of the collisions result in a reaction between particles
because the catalyst can lower the activation energy for the reaction.

Answer 2

They don't know what a catalyst is if they don't know how it works.

Answer 3

vice versa
