Is it true that the enthalpy change of a chemical reaction is calculated by subtracting the sum of bond dissociation energies of bonds formed from the sum of bond dissociation energies of bonds broken?

Yes. The enthalpy change of a chemical reaction is calculated by subtracting the sum of the bond dissociation energies of the bonds formed from the sum of the bond dissociation energies of the bonds broken.

Verdict: SUPPORTED · 2 sources for, 0 against · Last checked

The analysis

The claim states the standard thermochemical relationship where reaction enthalpy is estimated or calculated from bond dissociation energies by subtracting the bond energies of products (bonds formed) from reactants (bonds broken). Retrieved educational sources [8] and [9] explicitly outline this calculation method.
