WebLearn about and revise energy stores, transfers, conservation, dissipation and how to calculate energy changes with GCSE Bitesize Physics. 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.
WebThis is the amount of energy required to break the bond or the amount of energy given out when the bond is formed. This energy can be used to calculate how much heat would be released or absorbed in a reaction. To do this it is necessary to know the bonds present in both the reactants and products.
