The reaction enthalpy at 298 K relies on an activation energy of 167.4 kJ/mol and assumes a negligible activation barrier for product recombination. The enthalpy of formation relies on -723.9 ± 6.7 kJ/mol for the enthalpy of formation of Fe(CO)5(g). At least two other estimates of the activation energy for the Fe(CO)4(g) + CO(g) recombination have been reported: 7.1 kJ/mol Miller and Grant, 1985 and 16.7 kJ/mol Walsh, 1986. In Lewis, Golden, et al., 1984 authors have considered that the Fe(CO)4(g) fragment is in its singlet excited state. However, it has also been suggested that the fragment is formed in its triplet ground state Ray, Brandow, et al., 1988 Sunderlin, Wang, et al., 1992; MS

Henry's Law constant (water solution)

kH(T) = H exp(d(ln(kH))/d(1/T) ((1/T) - 1/(298.15 K)))
H = Henry's law constant for solubility in water at 298.15 K (mol/(kg*bar))
