WebVideo transcript. We saw in the last video that if we defined enthalpy, H, as being equal to the internal energy of a system plus the pressure of the system times the volume of the system-- and this is an almost arbitrary definition. But … WebThe Born-Haber cycle is an application of Hess’s law that breaks down the formation of an ionic solid into a series of individual steps: ΔH ∘ f, the standard enthalpy of formation of the compound. IE, the ionization energy of the metal. EA, the electron affinity of the nonmetal. ΔH ∘ s, the enthalpy of sublimation of the metal.
