Thermochemistry and Reaction Thermodynamics

This study guide covers Unit 6: Thermochemistry in AP Chemistry, focusing on energy and heat in chemical reactions. Key topics include: thermodynamics (exothermic and endothermic processes, First Law of Thermodynamics, thermal equilibrium), calorimetry (measuring heat with a calorimeter using q = mcΔT), and enthalpy (ΔH, calculating enthalpy using bond enthalpies, enthalpies of formation, and Hess's Law). The guide emphasizes calculations and the distinction between exothermic and endothermic reactions.
