WebHess's Law says that the overall enthalpy change in these two routes will be the same. That means that if you already know two of the values of enthalpy change for the three separate reactions shown on this diagram (the three black arrows), you can easily calculate the third - as you will see below. WebAug 2, 2024 · Introduction: Hess's Law states that regardless of the number of reaction steps, the total enthalpy (heat energy) change (∆H) for the overall reaction being considered, is always the same and equal to the sum of all the ∆H values for the all the individual steps. This law is a manifestation of enthalpy being a state function (like Gibbs ...
