- Exam practice and flashcards
- LESSON 1Born-Haber Cycles
Definitions of lattice and ionization enthalpies, cycle construction, and calculations.
- LESSON 2Enthalpies of Solution and Hydration
Analyse how ionic compounds dissolve, connecting lattice enthalpy and hydration enthalpies.
- LESSON 3Entropy
Understand entropy as disorder, predict the sign of entropy change, and calculate standard changes.
- LESSON 4Gibbs Free Energy
Calculate free energy changes, determine feasibility, and find the temperature at which reactions occur.
