Please read though chapters 5 and 19. You can hold off on anything after Page 830 (section 19.7) as we will come back to this and learn it with Equilibrium.
Major areas of focus include:
Enthalpy, Entropy, Laws of Themodynamics, Calorimetry, Endo vs. Exothermic Reactions, Stoichiometry with Energy Values.
You can play with the Calorimetry Virtual Lab to the right under simulations.
