In chemical reactions, heat is converted into chemical energy (the potential energy stored in chemical bonds) or vice versa. Bond energy is the energy required to break one mole of the bond in the gas phase. Since it takes energy to break a bond, bond energies are always positive. Conversely, energy is released when bonds are formed. Thus, the enthalpy change for a reaction can be approximated from Part C ΔΗΣ(ΔΗ breaking) + Σ(ΔΗ forming) Calculate the bond energy for forming all the bonds in a mole of water molecules, H20. where H represents bond energies for the breaking (positive bond energy) or forming (negative bond energy) of a bond and H; represents the overall enthalpy for the reaction.
