Calculating the Heat of Reaction from Bond Dissociation Energies

WebΔH° (bonds formed) = 331 kJ/mol + 431 kJ/mol = 762 kJ/mol. ΔH° (bonds broken) = 381 kJ/mol + 243 kJ/mol = 624 kJ/mol. We can see that ΔH° (bonds formed) > ΔH° (bonds broken). So, the bond dissociation energies of the products are higher ( stronger bonds) than the ones of starting materials. Remember, we mentioned that bond formation is ...
