Can you explain each of these out loud, without looking? If not, re-read that lesson.
- Enthalpy Changes: Measure heat changes with calorimetry and standard enthalpy definitions.
- Hess's Law: Calculate enthalpy changes indirectly using energy cycles.
- Rates of Reaction: Use collision theory to explain how reactions speed up.
- Chemical Equilibria: Apply Le Chatelier's principle and calculate equilibrium constants.
- Read each lesson's summary and re-do its practice questions from memory.
