Chapt. 15: Chemical Kinetics

1. Catalysis

2. Rate Laws: A Summary

3. Reaction Mechanisms

4. A Model for Chemical Kinetics

5. The Steady-State Approximation

6. Pseudo-first-order: make one reactant in a multireactant rxn rate-limiting

7. To test a proposed mechanism, compare the rate law of its slowest step with the experimentally determined rate law

8. Key Terms: elementary step, intermediate, molecularity & rate determining step

9. Reaction mechanisms can't be proven

10. At equilibrium: Keq=kforward/kreverse

11. Steady state: Rate of I production = Rate of I consumption

12. k=AExp(-Ea/RT)

13. Reaction Energy Diagram

14. Catalysts create a new reaction pathway with a lower activation energy

15. Reaction Rates

16. Rate Laws: An Introduction

17. Determining the Form of the Rate Law

18. The Integrated Rate Law

19. Rate=Change in Concentration/Time interval

20. Thermo: IF Kinetics: WHEN & HOW

21. Avoid complex kinetics by measuring initial rates

22. Rate Law: Rate=k[R]^n k & n must be determined experimentally

23. The rate law can provide information about the elementary steps of a reaction

24. Order=Sum of Exponents of Rate Law

25. 1st order half-life is independent of time or reactant concentration, 2nd order is not
