WebbWith Hess's Law though, it works two ways: 1. You use the molar enthalpies of the products and reactions with the number of molecules in the balanced equation to find the change in enthalpy of the reaction. That's what you were thinking of- subtracting the change of the products from the change of the reactants. 2.

WebbSo the bond enthalpy of the chlorine-chlorine single bond is equal to +242 kilojoules per mole. And what this means is, if we have one mole of chlorine-chlorine bonds, it takes +242 kilojoules of energy to break those bonds. Bond enthalpies are always positive because it takes energy to break bonds.
