University of Florida
General Chemistry I (CHEM 101) | Exam Review

Overview
A final exam review that helps students choose the right thermodynamics equation and interpret signs for ?H, ?S, and ?G quickly.

Key topics
•enthalpy and calorimetry basics
•entropy trends and sign prediction
•Gibbs free energy and spontaneity
•equilibrium link ?G? = -RTlnK

Suggested study tasks
•build a sign table for ?H ?S ?G cases
•solve one calorimetry heat problem
•connect ?G? to K for a reaction

Common pitfalls
•treating entropy like energy
•mixing standard vs nonstandard conditions
•using the wrong temperature units in RT
