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