🔬 Deep Dive: Collision Theory
For a reaction to occur, particles must:
| Condition 1 | Condition 2 |
|---|---|
| COLLIDE — particles must physically hit each other | HAVE ENOUGH ENERGY — energy must be ≥ activation energy (Ea) |
Successful collision = Reaction happens. More successful collisions per second = faster rate of reaction.
