WebHess's Law. Hess’s Law states that the enthalpy change for a chemical reaction is independent of the route taken. This means that the enthalpy change for the overall … WebHess’s law states that when chemical equations are combined algebraically, their enthalpies can be combined in exactly the same way. Two corollaries immediately present themselves: If a chemical reaction is reversed, the sign on Δ H is changed. If a multiple of a chemical reaction is taken, the same multiple of the Δ H is taken as well.
