1. Chemical Kinetics
The rate or speed of chemical reactions - experimental & graphical
How to control or influence the rate - faster or slower
The mechanism of the reaction - atomic/molecular level picture of how reactions occur (organic chem.)

2. Investigating a Simple Reaction
A2(g) B2(g) AB(g)
molecular view
How is the reaction going to occur?

3. possible collisions

4. an effective
collision
Activated complex-
hypothetical
comes
apart

5. In any chemical reaction:
bonds break - this requires energy
bonds form - this releases energy
overall for the reaction
exothermic reaction - releases energy
endothermic reaction - absorbs energy
Is there an energy barrier to overcome?
