## What is Rates of Reaction?

Rates of Reaction gives you a model of the collision theory to explain with and explore. You’ll use it to cover:
•	How particles must collide in order to react
•	Which factors affect the frequency of collisions
•	How real reactions compare to a model reaction
•	How activation energy affects the rate of reaction
•	How only collisions with sufficient energy lead to a reaction

## Key features

- Collision theory model
- Factors affecting collision frequency
- Activation energy simulation
- Model vs. real reaction comparison
- Particle collision explanation
