UNC CHEM 102: General Descriptive Chemistry II
CHEM 102 completes UNC's general chemistry pair — kinetics, equilibrium, acids and bases, thermodynamics, and electrochemistry — with the lab (CHEM 102L) separate. It's the direct gatekeeper to organic chemistry and the course where gen chem turns conceptual.

Build my CHEM 102 study planWhat makes it hard
Equilibrium is the spine of the course and the wall: ICE tables, acid-base systems, and buffers all run on it, so a wobbly equilibrium foundation makes every later unit harder. The math shifts too — logarithms and exponents everywhere — and exam problems chain concepts (a kinetics result feeding an equilibrium question) in ways single-topic homework never rehearsed.

- • Chemical equilibrium
- • Acids, bases, and buffers

The CHEM 102 study guide
How to study for UNC CHEM 102, step by step.
- 1
Overlearn equilibrium when it arrives
Acids, bases, buffers, and solubility all run on the equilibrium engine. ICE-table fluency and a real grasp of Le Chatelier are the difference between one hard unit and four.
- 2
Rehab logs and exponents before acid-base
pH, pK, and equilibrium constants live in log-space, and rusty log algebra silently corrupts otherwise-correct chemistry. Drill the manipulations before the unit assumes them.
- 3
Practice chained, multi-concept problems
Exam questions connect kinetics to equilibrium to thermodynamics in single problems. Seek out chained practice deliberately — single-topic homework never rehearses the integration exams test.
- 4
Track the conditions on every equation
Free energy, the Nernst equation, and equilibrium relations each hold under specific conditions. Note the when alongside the what — condition-violations are a reliable exam trap.
- 5
Keep first-semester skills warm
Stoichiometry and gas-law fluency from CHEM 101 are assumed inside 102's problems. A short weekly refresher keeps old tools sharp while new concepts pile on.

How Fennie helps with CHEM 102
Fennie's Daily Plans front-load CHEM 102's equilibrium spine and schedule the chained-problem practice its exams actually test, paced to your exam dates. Chat works ICE tables and buffer systems step by step with the log-math made explicit, and generated quizzes integrate concepts the way exam questions do — not the way single-topic homework does.
FAQ
Is CHEM 102 harder than CHEM 101?
Most students say yes: the course turns conceptual, equilibrium underpins everything, and exam problems chain multiple topics together. Students who overlearn equilibrium when it arrives find the back half manageable; those who wobble through it fight every unit after.
How do I study for CHEM 102 exams?
Drill ICE tables and equilibrium reasoning until automatic, rehab logarithm algebra before acid-base, and practice multi-concept chained problems deliberately. Keep CHEM 101 stoichiometry warm — it's assumed silently inside nearly every 102 problem.
Do I need CHEM 102 before organic chemistry?
Yes — the general chemistry sequence gates CHEM 261, and organic leans on 102's equilibrium and acid-base thinking constantly. Going into orgo with weak acid-base intuition is one of the classic pre-health mistakes.

CHEM 101 — General Descriptive Chemistry I
CHEM 101 is UNC's first general chemistry course — stoichiometry, atomic structure, periodicity, bonding, and thermochemistry — the opening gate of the pre-health and science sequences, taken in large lectures with the lab (CHEM 101L) as a separate course.
CHEM 261 — Introduction to Organic Chemistry I
CHEM 261 is UNC's first organic chemistry course — structure and bonding, stereochemistry, substitution and elimination, and the beginnings of reaction mechanisms — the most mythologized course on the pre-health track, with exams that reward reasoning over recall.
