  1. 4. atoms, ions, and molecules can react to form products when they collide if the particles have enough kinetic energy.
  2. 6. decreasing particle size increases _____ for a given mass of particles.
  3. 8. reaction that absorbs heat
  4. 9. a measure of how much something changes within a specified amount of time.
  5. 11. the minimum energy that colliding particles must have in order to react
Down
  1. 1. reaction that releases heat
  2. 2. the number of particles in a given volume
  3. 3. a substance that interferes with the action of a catalyst.
  4. 4. increases the rate of a reaction by lowering the activation energy. It is a substance that does not get consumed by the reaction.
  5. 5. catalysts that increase the rates of biological reactions
  6. 7. measure the average kinetic energy of particles in a sample
  7. 10. unstable arrangement of atoms that forms for a moment at the peak of the activation-energy barrier.
