A scientist measures the standard enthalpy change for the following reaction to be - 773.4 kJ: 2NO(g) + 2H₂(g) → N₂(g) + 2H₂O (1) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of H₂O(l) is kJ/mol. Substance AH (kJ/mol) NO(g) H₂ (9) N₂ (9) 90.3 0.0 0.0
A scientist measures the standard enthalpy change for the following reaction to be 77.5 kJ: 2CO2(g) + 5H2(g) → C₂H2(g) + 4H₂O(g) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of CO₂(g) is kJ/mol Species AH (kJ/mol) C₂ H₂ (9) H₂O(g) H₂ (9) 226.7 -241.8 0.0
