AP Chemistry

Connect particle-level models, measurements, reactions, energy, rates, equilibrium, and electrochemistry to explain observable chemical behavior.

Course map

Open a section, then choose the exact idea.

Use moles, spectra, electron configurations, and periodic patterns to connect atomic-scale structure with measurable elemental properties.

Relate bonding, potential energy, solid structures, Lewis representations, resonance, and molecular geometry to compound properties.

Explain phases, gases, solutions, solubility, separation, and spectroscopy through intermolecular forces and particle-level representations.

Represent and quantify chemical change using equations, stoichiometry, titration, acid-base chemistry, and oxidation-reduction reasoning.

Model how concentration, collisions, energy profiles, mechanisms, and catalysts determine reaction rates over time.

Track heat and enthalpy across physical and chemical changes using calorimetry, bond energies, formation data, and Hess’s law.

Describe reversible systems quantitatively and predict how concentrations, quotients, constants, and disturbances affect equilibrium.

Use equilibrium models to analyze acid-base strength, pH, titrations, molecular structure, buffers, capacity, and solubility.

Connect entropy, Gibbs free energy, equilibrium, coupled processes, and electrochemical cells to the direction and work of reactions.
