Total reaction energy is typically calculated using the bond energies of the reactants and products involved in a chemical reaction. The correct formula for calculating the total reaction energy is:
**Reactant bond energy - Product bond energy.**
This means you take the total bond energies of the reactants, which represents the energy required to break those bonds, and subtract the total bond energies of the products, which represents the energy released when those bonds are formed.
Thus, the formula is:
\[
\text{Total Reaction Energy} = \text{Bond Energy of Reactants} - \text{Bond Energy of Products}
\]
This calculation provides insight into whether the reaction is exothermic (releases energy) or endothermic (absorbs energy).
