(Note: This does not include calculating the total bond energy changes.) Breaking bonds requires an input of energy from the system or surroundings, and forming bonds releases energy to the system and the surroundings. The energy transfer between systems and surroundings is the difference in energy between the bond energies of the reactants and the products. Energy transfer occurs during molecular collisions.
