Hess’ Law of Heat Summation Hess’ Law states that: "The enthalpy change for any reaction depends on the products and reactants and is independent of the pathway or the number of steps between the reactant and product". BASICALLY: Hess’ Law states "the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps" >This is also known as the "law of constant heat summation". All it means is that no matter how many steps the chemical
