What is the most important application of Hess’s law? Applications of Hess’s Law: WebA) Internal energy is a default function. - True, inhouse energy depends only upon the current state of one system, not on this track taken to outreach that state. B) The calorimetry change for one reaction is equal in magnitude, but opposite in sign, to the enthalpy change with the invert reaction. - True, this is a consequence of Hess's law.
