Across
  1. 2. the minimum amount of energy required to initiate a chemical reaction
  2. 5. the step-by-step sequence of elementary reactions by which overall chemical changes occur
  3. 6. a substance that increases the rate of a chemical reaction without undergoing a chemical change itself
  4. 7. the total area of exposed surfaces of a solid, which can affect the rate of reactions occurring at a solid surface
Down
  1. 1. the amount of a substance present in a given volume of solution, which can affect the rate of reaction
  2. 3. the measure of average kinetic energy
  3. 4. the slowest step in a reaction mechanism that determines the overall rate of the reaction
  4. 8. the theory that explains how chemical reactions occur and why rates differ
