📘 WHAT YOU GET:

30 pages of expertly designed practice problems taking you from basic concepts to AP exam mastery. Strategic progression with 150+ questions covering every Unit 9 topic.

⚡ WHY UNIT 9 IS TOUGH:

Unit 9 combines thermodynamics + electrochemistry with complex relationships between ΔG, E°, and K. One wrong formula = entire problem wrong. This workbook teaches you which formula to use when.

📚 WHAT'S INSIDE:

THERMODYNAMICS (Pages 1-8):

Entropy predictions and ΔS° calculations
Gibbs Free Energy (ΔG = ΔH - TΔS)
Four scenarios for spontaneity
Kinetic vs thermodynamic control
ΔG° and K relationship
Coupled reactions (ATP)
Integration review

ELECTROCHEMISTRY (Pages 9-20):

Galvanic cells (anode/cathode, notation)
E°cell calculations
ΔG° = -nFE° relationship
Nernst equation (concentration effects)
Electrolytic cells
Faraday's laws (Q = It, mass deposited)
E° and K connections

ADVANCED PRACTICE (Pages 21-24):

16 comprehensive multi-part integration problems
Mix all concepts in complex scenarios
No answer keys (test yourself!)

AP EXAM PREP (Pages 25-28):

12 authentic AP-style free response problems
Multi-part questions with explanations
Matches real AP exam format and difficulty

REFERENCE (Pages 29-30):

💯 WHAT MAKES IT DIFFERENT:

✅ 5-6 questions per page (not overwhelming)
✅ Answers included on concept-building pages
✅ Progressive difficulty - basic → AP level
✅ Strategic repetition - formulas appear 3-4 times
✅ Manga-style - engaging and proven effective
✅ 100% AP-aligned - only tested topics

📊 BY THE NUMBERS:

30 pages
150+ questions
12 AP exam-style problems
12 comprehensive integration problems
Complete formula reference sheet
Black-and-white (print-friendly)

🎯 YOU'LL MASTER:
