WebJul 28, 2024 · The standard enthalpy of formation of all stable elements (i.e., O 2, N 2, C, and H 2) is assumed as zero because we need no energy to take them to that stable state under our atmospheric conditions. For a reaction, the enthalpy change formula is: ΔH°reaction = ∑ΔH°f(products) - ∑ΔH°f(reactants) where: WebThat's their heats of formation. So Hess's Law tells us that delta H of this reaction, the change in enthalpy of this reaction, is essentially going to be the sum of what it takes to decompose these guys, which is the minus heat of formations of these guys, plus what it takes to reform these guys over here. So we can just write it as delta H of ...
