Explore the relationship between heat transfer and chemical reactions. Learn about enthalpy, entropy, and Gibbs free energy, and how they influence the spontaneity of reactions.
Thermochemistry 1. Definition Thermochemistry is the branch of physical chemistry that deals with the study of the heat changes that occur during chemical reactions and phase transitions. 2. Key Concepts a. Heat (q) Heat is a form of energy that flows from a warmer object to a cooler object. In thermochemistry, heat is commonly measured in joules (J) or calories (cal). b. Enthalpy (ΔH) Enthalpy...…
