Breakdown of AP Chemistry Units?

Hi! I'm taking AP Chemistry next year and I'm trying to get a head start. I'm looking for a breakdown of the major units covered in the curriculum. If anyone could share what topics to expect and maybe some tips on what I should focus on over others, I'd greatly appreciate it!

Sure, it's wonderful that you're being proactive and getting a head start on your AP Chemistry studies! Here is a rough breakdown of the course's main units along with the estimated weighting in the exam:

1. Atomic Theory and Structure (7-9% of the exam) – This unit includes topics like isotopes, electronic structure, and periodic trends.

2. Molecular and Ionic Compound Structure and Properties (7-9%) – Here you'll dive into concepts like molecular formulas, Lewis diagrams, and polarity.

3. Intermolecular Forces and Properties (18-22%) – This unit will cover topics on solids, liquids, gases, and solution types including phase changes and vapor pressure.

4. Chemical Reactions (7-9%) – Topics under this unit involve chemical equations, stoichiometry, and the types of chemical reactions.

5. Kinetics (7-9%) – Major topics in this unit include reaction rates, collision theory, and reaction mechanisms.

6. Thermodynamics (7-9%) – You'll learn about enthalpy, entropy, Gibbs Free Energy, and Hess’s law in this unit.

7. Equilibrium (7-9%) – Equilibrium expressions, calculations, and disturbances such as Le Chatelier's Principle are all part of this unit.

8. Acids and Bases (11-15%) – This is a significant unit that covers the pH scale, acid and base strengths, and titrations.

9. Applications of Thermodynamics (7-9%) – This unit is all about applications, mainly Ksp, pH and pOH, and Electrochemistry.

10. Organizational Chemistry (2-3%) – The final unit introduces you to the naming and structure of organic compounds.

For success in AP Chemistry, focus on understanding the fundamental concepts behind these units in order to interpret and solve problems. Practice problems and AP practice exams are vital to gauge your understanding and get used to the exam format. Also, familiarize yourself with the periodic table and all its traits - it is pivotal in AP Chemistry! Remember to use reliable resources to study and avoid cramming big topics at the last minute. All the best in your study journey!
