Across
- 3. area This factor increases the rate of reaction. Powder has a greater___________than small and large chips
- 5. Is a biological catalyst
- 8. This is measured using a stop watch to find out the rate of reaction
- 9. When reactant particles bump into each other
- 10. A substance that is formed in a chemical reaction. Formed after a successful collision.
- 11. The number of times per second
Down
- 1. This factor increases the rate of reaction and is used to define the amount of particles in a certain volume
- 2. This speeds up the rate of the reaction without being used up in the reaction
- 4. This factor increases the rate of reaction by making the particles move around quicker. This means they collide more frequently and with more energy.
- 6. A substance that takes part in and undergoes change during a reaction. These particles collide during a reaction
- 7. The speed of the reaction
