Definition of bond enthalpy

Postby Claire_Zhou_1A » Sat Jan 14, 2017 11:17 am

So I read on the textbook that bond enthalpy is the difference between standard molar enthalpy of molecules and its fragments in gas phase. Is this the same as the energy required to break the bond?

That is correct! On page 16 of the course reader Dr. Lavelle discusses bond enthalpies, highlighting that energy is required to break bonds (+ΔH) and that energy is released when a bond is formed (- ΔH).

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
