Chemical Energetics: Exothermic and Endothermic | IGCSE and O Level Chemistry pptx
Bond Energies and Calorimetry Insights
Summary: This presentation explores exothermic and endothermic reactions by detailing how energy is absorbed to break bonds and released when new bonds form. It covers key concepts like bond energy, heat of reaction, and heats of combustion, along with the use of bomb calorimeters, Hess’s Law, and the law of conservation of energy to explain chemical energy changes.
