WebDec 9, 2024 · 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 ΔH = +679 kJ - 862 kJ ΔH = -183 kJ Answer WebEven so, it can be calculated with the help of the Born-Haber cycle. Generally, it is expressed as kilojoules per mole (kJ/mol). Lattice Energy Definition Lattice Energy definition can be explained in two distinct ways by a sort of potential energy.
