WebThe changes in energy that occur during a chemical reaction can be seen by examining the changes in chemical bonding. This can be used to classify reactions as exothermic or endothermic. WebEnergy of bonds in products = (2 x C=O) + (4 x H-O) = (2 x 532) + (4 x 465) = 2924 kJ / mol. Step 4: Work out the energy change. Difference = 2924 - 2644 = 280 kJ / mol . Since the reaction is exothermic, the bonds must have less energy at the end than at the start. We write the bond energy change as - 280 kJ / mol.
