Units

1. UNIT 01

   Intermolecular forces and solutions

   Intermolecular forces explain boiling points, solubility and other physical properties, and solutes change a solvent's properties.
2. UNIT 02

   Chemical kinetics

   Kinetics studies how fast reactions happen and why, through rate laws, activation energy and reaction mechanisms.
3. UNIT 03

   Chemical equilibrium

   At equilibrium, forward and reverse rates are equal, and the equilibrium constant describes the balance of products and reactants.
4. UNIT 04

   Acids and bases

   Acids donate protons and bases accept them; pH measures acidity, and Ka and Kb describe the strength of weak acids and bases.
5. UNIT 05

   Buffers, titrations and solubility

   Buffers resist pH changes, titrations measure unknown concentrations, and Ksp describes how much of a slightly soluble salt dissolves.
6. UNIT 06

   Thermodynamics: entropy and free energy

   Entropy and Gibbs free energy determine whether a reaction is thermodynamically favored and how it relates to equilibrium.
7. UNIT 07

   Electrochemistry

   Electrochemistry uses redox reactions to produce electricity in galvanic cells or uses electricity to drive reactions in electrolysis.
