Element/ Compound Standard Heat of Formation (kJ/mol) Element/ Compound Standard Heat of Formation (kJ/mol)
H(g) 218 N(g) 473
H2(g) 0 O2(g) 0
NH3(g) −45.90 O(g) 249
CO(g) −110.5 H2O(g) −241.8kJ
C(g) 71 HCN(g) 130.5kJ
C(s) 0 HNO3(aq) −206.6
Express the standard enthalpy of reaction to three significant figures and include the appropriate units.
