Thermochemistry Overview Thermochemistry is the study of heat energy changes that occur during chemical reactions and physical transformations. It bridges chemistry and thermodynamics, focusing on the energy flow between chemical systems and their surroundings. Key Concepts Enthalpy (H) Heat content of a system at constant pressure ΔH = heat absorbed or released during a reaction Exothermic reactions: ΔH < 0 (release heat) Endothermic reactions: ΔH > 0 (absorb heat) Hess's La
