1
Q
Activation energy
A
The minimum amount of energy required for particles to collide successfully and cause a reaction.
2
Q
Catalyst
A
A substance that increases the rate of a reaction without being changed in chemical composition or amount. It works by providing an alternative reaction pathway with a lower activation energy.
3
Q
Collision theory
A
Reactions occur only when particles collide with sufficient energy (activation energy).
