Webthe concept of a state function. Hess’s Law states that if a reaction can be expressed as the sum of two other reactions, then the enthalpy change for that reaction can be calculated … WebHess' law allows the enthalpy change (ΔH) for a reaction to be calculated even when it cannot be measured directly. This is accomplished by performing basic algebraic operations based on the chemical equation of reactions using previously determined values for the enthalpies of formation.
