WebAug 15, 2024 · Step 1- First look at the equation and identify which bonds exist on in the reactants (bonds broken). one H-H bond and one Br-Br bond Step 2- Do the same for the products (bonds formed) two H-Br bonds Step 3- Identify the bond energies of these bonds from Table 7.4. 1: H-H bonds: 105 kcal/mol Br-Br bonds: 46 kcal/mol WebBond energy is the measure of a bond’s strength; the bigger the bond energy, the stronger the chemical bond. If the bond energy of a chemical bond is negative, the bond cannot exist because it will be too unstable. Therefore, it is almost impossible for a chemical bond to have a negative value for its bond energy. can beef stew be frozen after cooked
