Bond enthalpy vs Bond Enregy

Postby Schuyler_Howell_4D » Mon Feb 04, 2019 8:26 pm

Are bond enthalpy and bond energy the same thing? If not what is the difference?

I believe they are the same thing. Bond enthalpy/energy is the energy required to break one mole of a bond.

Hello!

Bond enthalpy is the amount of energy needed to break 1 mol of a specific bond for gaseous atoms under standard conditions. These always have positive values, since bond breaking requires energy and is thus endothermic.

Bond energy is more ambiguous. It could mean the amount of energy a bond holds, in which case would be the same as the bond enthalpy, or it could be the strength of the bond (weak, strong).

Hope this helps :)

Are both bond enthalpy and bond energy always positive?
