📌 Key Facts: Factors Affecting Rate
- Temperature ↑ → particles faster + more have Ea → more successful collisions
- Concentration ↑ → more particles per volume → more frequent collisions
- Surface area ↑ → more exposed particles → more collisions at once
- Catalyst → lowers Ea → more particles can react
- Pressure ↑ (for gases) → same effect as concentration
- Catalysts are specific — each catalyst only works for certain reactions
- Enzymes are biological catalysts
