Probability density of electron orbit
- Electrons do not travel in simple circular orbits
previously believed.
- Probability density defines that you are more likely
to encounter an electron at a point in space where

3. Principles of reaction Kinetics
The rate of reaction (ROR) is dependent on the concentration of reactants. This can be explained
using collision theory.
When concentration is decreased, the number of particles available for collision will be reduced.
