GCSE Chemistry - Bond Energies #44 (Higher tier)

The video tutorial explains bond energies and their significance in determining whether a chemical reaction is exothermic or endothermic. It describes bond energy as the energy required to break one mole of a covalent bond and highlights that breaking bonds is endothermic while forming bonds is exothermic. The tutorial provides examples of reactions, such as hydrogen with chlorine and nitrogen with hydrogen, to demonstrate how to calculate the overall energy change by comparing the energy required to break bonds with the energy released during bond formation.
