Collision theory and energy profile diagrams

What this note covers

1. Collision theory explains why only some collisions react
2. Temperature changes the energy distribution
3. Catalysts and enzymes provide a lower-energy pathway
4. Energy profiles show Ea and ΔH separately
5. Rate is obtained from the slope of a quantity–time graph
6. Designing and evaluating a rate investigation
7. Obtaining rates from gas-volume measurements
8. Forward and reverse barriers on one energy profile
