Enthalpy is a state function because it is defined in terms of state functions. U, P, and V are all state functions. Their values depend only on the state of the system and not on the paths taken to reach their values. A linear combination of state functions is also a state function. Enthalpy is defined as H = U + PV.

H 2 (g) + 1/2O 2 (g) → H 2 O (g) ΔH° = -572 kJ. When switched: H 2 O (g) → H 2 (g) + 1/2O 2 (g) ΔH° = +572 kJ. Since enthalpy is a state function, it is path independent. Therefore, it does not matter what reactions one uses to obtain the final reaction.

WebBefore we can answer this question, let's define path and state functions: path function are quantities that depend on the path that was taken from the initial state to the final state. For example, heat and work are path functions. state functions are quantities that don't depend on the path that was taken from the initial to the final state. They only depend on …
