Bond Enthalpy vs. Bond Dissociation Enthalpy

Postby Andres Reynoso 1J » Sat Jan 13, 2018 5:42 pm

What is the difference between these two terms? I do not think bond dissociation enthalpy has not been discussed in class but I came across the term reading online and am curious.

I believe the two terms are interchangeable

I believe there is a difference between the two. Bond enthalpy refers to the amount of energy it takes to break one mole of a bond. On the other hand, Bond Dissociation Enthalpy is referring to the enthalpy change as two atoms that were previously bonded retain the electron they put into the bond in the first place. The important thing to note here is that Bond Enthalpy averages the bond dissociation enthalpies of all the bonds in a molecule while bond dissociation enthalpy refers to one single chemical bond.

These words are the same.
