Hess’s law is the manifestation of the fact that enthalpy is a state function. This concept can be extended to other state functions, like entropy, Gibbs free energy, and Helmholtz free energy. The change in entropy of a reaction as follows: ΔSrxn = ∑ΔS (prod) − ∑ΔS (react)

WebOct 21, 2015 · The typically unstated assumption in applying Hess's law is that you are going from an initial state of pure reactants (say, in separate containers) to a final state of pure products (also in separate containers). In the case of ideal gas reactions, the enthalpy of mixing is zero and enthalpy is independent of pressure.
