The average sf bond energy
WebApr 4, 2024 · The average of bond dissociation enthalpies is referred to as bond energy or bond enthalpy for a given compound or molecule. Bond energies are closely related to the stability of the atom or molecule. The higher the bond energy, the stronger the chemical bond and the more difficult it will be to cleave the bond. WebFor example, the sum of the four C–H bond energies in CH 4, 1660 kJ, is equal to the standard enthalpy change of the reaction: The average C–H bond energy, D C–H, is 1660/4 = 415 kJ/mol because there are four moles of C–H bonds broken per mole of

Bond breaking liberates energy, so we expect the ΔH for this portion of the reaction to have a negative value. Using the table, the single bond energy for one mole of H-Cl bonds is found to be 431 kJ: ΔH 2 = -2 (431 kJ) = -862 kJ. By applying Hess's Law, ΔH = ΔH 1 + ΔH 2.
