Unit practice sets
Each AP unit has a complete practice set. Attempt every problem first, then open the separate step-by-step solutions.
-
Unit 1
Atomic Structure and Properties
Turn measurable masses and spectra into claims about particle numbers, composition and electronic structure.
-
Unit 2
Compound Structure and Properties
Connect electron arrangements to bonding, potential energy, crystal behavior and molecular shape.
-
Unit 3
Properties of Substances and Mixtures
Use particle interactions, gas laws, solution models and light measurements to explain and measure bulk properties.
-
Unit 4
Chemical Reactions
Follow atoms, charge, protons, electrons, and amounts through reactions; use observations without overclaiming what they prove.
-
Unit 5
Kinetics
Connect measured reaction progress to empirical rate laws, particle collisions, and testable elementary-step mechanisms.
-
Unit 6
Thermochemistry
Account for energy across a chosen boundary, infer reaction heat from measured temperature data, and connect phase, bond, formation and Hess calculations.
-
Unit 7
Equilibrium
Explain a changing mixture with competing molecular events, use Q and K to calculate its composition, and reason about stresses and solubility.
-
Unit 8
Acids and Bases
Track proton transfer, select the correct pH model, interpret titrations and buffers, and explain how structure and pH change chemical behavior.
-
Unit 9
Thermodynamics and Electrochemistry
Use entropy and free energy to explain equilibrium and energy conversion, then connect balanced redox reactions to cell operation, voltage, and charge.
