Presentation Transcript

Kinetics

- Answers question, “How fast?”
- Rate is proportional to the concentration of reactants raised to a power.
- Rate law is experimentally determined.=>

Activation Energy

- Minimum energy required to reach the transition state.
- At higher temperatures, more molecules have the required energy.

Reaction-Energy Diagrams

- For a one-step reaction:reactants transition state products
- A catalyst lowers the energy of the transition state.

Rate-Limiting Step

- Reaction intermediates are stable as long as they don’t collide with another molecule or atom, but they are very reactive.
- Transition states are at energy maximums.
- Intermediates are at energy minimums.
- The reaction step with highest Ea will be the slowest, therefore rate-determining for the entire reaction. =>
