Hess's law states that the change of enthalpy in a chemical reaction is the same regardless of whether the reaction takes place in one step or several steps, provided the initial and final states of the reactants and products are the same. Enthalpy is an extensive property, meaning that its value is proportional to the system size. Because of this, the enthalpy change is proportional to the number of moles participating in a given reaction. Webb20 dec. 2024 · IF the total heat capacities of reagents and products were by chance equal, the reaction enthalpy would be temperature independent. But as these total heat …
