WebHess’s law is also known as Hess’s law of constant heat summation, and it is an example of the law of conservation of energy. Hess’s law will always apply to an energy cycle, provided that the initial and final conditions are the same for each pathway taken. WebHess’s law allows us to combine reactions algebraically and then combine their enthalpy changes the same way. Exercises Define Hess’s law. What does Hess’s law require us to do to the Δ H of a thermochemical equation if we reverse the equation? If the Δ H for C2H4 + H2 → C2H6 is −65.6 kJ, what is the Δ H for this reaction? C2H6 → C2H4 + H2
