A scientist measures the standard enthalpy change for the following reaction to be 316.2 kJ: H₂S(g) + 2H₂O(1)→ 3H₂(g) + SO₂(g) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of H₂O(l) is Species AH (k/mol) H₂(g) SO₂ (9) H₂S(g) 0.0 -296.8 -20.6 kJ/mol.
