Across
- 3. a measurement clearly out of line with the trend
- 6. a collision between particles that leads to a reaction
- 7. a poor measurement (human error)
- 9. a statement suggesting what will happen in the future
- 10. the minimum amount of energy needed for a reaction to take place
- 12. think about the method you used and how it could be improved
- 14. the thing that you change
- 15. the number of particles per unit volume
- 16. the exterior of a solid that can react with other substances
Down
- 1. problem with the apparatus
- 2. the gap between the readings
- 4. speeds up a chemical reaction by lowering the activation energy
- 5. a collision between particles that doesn’t lead to a reaction
- 8. the number of collisions taking place per unit time
- 11. the amount of product formed or reactant used up over time
- 13. the thing that you measure
