WebHess' law tells us that any difference in energy converting between two substances is independent of the route taken for the conversion. An energy cycle is a diagram showing how three, or more reactions are interconvertable. WebHess's law can be used to determine the overall energy required for a chemical reaction that can be divided into synthetic steps that are individually easier to characterize. This …
WebIn Chemistry, what you often do is take a compound and break it down to individual atoms first because you know the enthalpies for bond formations or otherwise enthalpies of individual reactions. Then you take these atoms and form the products made. You effectively do: Reactants -> Atoms -> Products, which is the equivalent of Reactants -> Products
