Web aqa calculating bond energy | teaching resources. Bond energy is the amount of energy needed to break one. Different bonds have different bond energies. Calculate the energy released when the bonds in products are made. Bond energies are reported in kilojoules per mole (kj/mol).
You can calculate the energy change in a reaction using average bond energies. Web students will recall energy level diagrams, describe what happens to chemical bonds during exothermic and endothermic reactions, and use ideas about bond energies to explain energy changes in chemical reactions. The opposite occurs for forming bonds as it releases energy back to the surroundings in an exothermic process. If the energy used to break bonds is greater than the energy released in the formation of new bonds, is the reaction endothermic or exothermic?
If the energy used to break bonds is greater than the energy released in the formation of new bonds, is the reaction endothermic or exothermic? Web bond energy calculations 2. Calculate the energy released when the bonds in products are made.
