Individual Reactions
C4H2FeO4 (g) = 2 (g) + C4FeO4 (g)
By formula: C4H2FeO4 (g) = 2H (g) + C4FeO4 (g)

ΔrH° | 545. | kJ/mol | EST | Miller and Beauchamp, 1991 | Please also see Martinho Simões and Beauchamp, 1990. The reaction enthalpy was estimated from the activation enthalpy for thermal decomposition in solution, 109. ± 8. kJ/mol Pearson and Mauermann, 1982, yielding Fe(CO)4 and H2, and from the activation enthalpy of the oxidative addition of H2 to Fe(CO)4 in a rare gas matrix, ca. 0. kJ/mol Sweany, 1981, yielding Fe(CO)4H2. The enthalpy of formation relies on -440. ± 14. kJ/mol for the enthalpy of formation of Fe(CO)4(g) |
