WebNov 26, 2024 · equation 1: P4 + 5O2 → 2P2O5 ΔH1 equation 2: 2P2O5 + 6H2O → 4H3PO4 ΔH2 equation 3: P4 + 5O2 + 6H2O → 3H3PO4 ΔH3. Enthalpy is a state function which means the energy change between two states is independent of the path. Since equation 1 and 2 add to become equation 3, we can say: ΔH3 = ΔH1 + ΔH2.
