Calorimetry and hess's law

WebIn the previous post, we talked about the Hess’s law and how it can be used for measuring the enthalpy change (ΔH) for a reaction without making calorimetric measurements.. In … 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.
