Across
- 2. The forces between particles that are rearranged in a chemical reaction
- 3. When there are smaller pieces of a chemical, more of it can react- so the rate increases
- 5. The minimum amount of energy a chemical needs to react
Down
- 1. More particles in a smaller space
- 4. How quick a reaction is
- 6. Gives a higher rate of reaction without increasing the activation energy
- 7. This makes the particles vibrate and bump into each other, increasing the rate of reaction
- 8. When a reaction absorbs more heat than it releases
- 9. When a reaction gives out heat
