WebBond enthalpy is the energy that it takes to break one mole of a bond. So one mole of a bond. So different types of bonds will have different bond enthalpies. So as an example, we can talk about a carbon hydrogen bond, or a carbon hydrogen single bond. WebThe mean bond enthalpy gives an average value you can use for your calculations for the C-C bond in any molecule. It's worked out 'over a range' of molecules and you don't need to know any more than that. Just that it's an average, and therefore the calculations you make using the value are estimates.
