  1. 3. The particular arrangement of reactant and product molecules at the point of maximum energy in the rate-determining step of a reaction
  2. 6. An equation that relates the rate constant for a reaction to the frequency factor, A, the activation energy, , and the temperature, T; : k = Ae^(-E/RT)
  3. 8. The slowest elementary step in a reaction mechanism
  4. 11. A detailed picture, or model, of how the reaction occurs; that is, the order in which bonds are broken and formed and the changes in relative positions of the atoms as the reaction proceeds
  5. 13. A protein molecule that acts to catalyze specific biochemical reactions
  6. 15. A substance that undergoes a reaction at the active site in an enzyme
  7. 17. The area of chemistry concerned with the speeds, or rates, at which chemical reactions occur
  8. 18. A reaction in which the reaction rate is proportional to the concentration of a single reactant, raised to the first power
  9. 20. A substance that changes the speed of a chemical reaction without itself undergoing a permanent chemical change in the process
Down
  1. 1. An elementary reaction that involves a single molecule
  2. 2. A constant of proportionality between the reaction rate and the concentrations of reactants that appear in the rate law
  3. 4. A measure of the decrease in concentration of a reactant or the increase in concentration of a product with time
  4. 5. An equation that relates the reaction rate to the concentrations of reactants
  5. 7. A substance formed in one elementary step of a multistep mechanism and consumed in another
  6. 9. The number of molecules that participate as reactants in an elementary reaction
  7. 10. A term in the Arrhenius equation that is related to the frequency of collision and the probability that the collisions are favorably oriented for reaction
  8. 12. A reaction in which the overall reaction order in the rate law is 2
  9. 14. A model of reaction rates based on the idea that molecules must collide to react
  10. 16. The minimum energy needed for reaction; the height of the energy barrier to formation of products
  11. 19. The time required for the concentration of a reactant substance to decrease to half its initial value
