Across
  1. 5. Minimum energy for a reaction to occur
  2. 6. these have positive delta H values
  3. 9. decreasing this increases the surface area of solids
  4. 10. increases rate of reaction while remaining chemically unchanged, enzymes are biological examples
  5. 11. increasing this increases concentration and also rate of reaction
Down
  1. 1. what is achieved when reactants achieve minimum amount of energy to react
  2. 2. Particles need to do this to react
  3. 3. effectiveness of a collision depends on the g______y of the reacting particles
  4. 4. rate of reaction depends on f________y of collisions
  5. 7. these have negative delta H values
  6. 8. Distribution showing number of particles with a certain kinetic energy
