This topic explores the thermodynamics of chemical reactions, focusing on the transfer of thermal energy between the reacting system and the surroundings. Students investigate the distinction between exothermic and endothermic processes through experimental calorimetry and theoretical reaction profiles, adhering to the Law of Conservation of Energy. The content extends to the quantitative analysis of bond enthalpies, requiring the calculation of overall energy changes based on the fundamental principle that bond breaking is endothermic while bond making is exothermic.
