Individual Reactions

C12H16O5W (solution) = C5O5W (solution) + (solution)

By formula: C12H16O5W (solution) = C5O5W (solution) + C7H16 (solution)

Quantity	Value	Units	Method	Reference	Comment
ΔrH°	56.1	kJ/mol	N/A	Morse, Parker, et al., 1989	solvent: Heptane; The reaction enthalpy was derived by using the LPHP value for the enthalpy of cleavage of W-CO bond in W(CO)6, 192.5 kJ/mol Lewis, Golden, et al., 1984, toghether with a PAC value for the reaction W(CO)6(solution) + n-C7H16(solution) = W(CO)5(n-C7H16)(solution) + CO(solution), 136.4 kJ/mol Morse, Parker, et al., 1989

(solution) + (solution) = C12H16O5W (solution) + (solution)

By formula: C6O6W (solution) + C7H16 (solution) = C12H16O5W (solution) + CO (solution)

Quantity	Value	Units	Method	Reference	Comment
ΔrH°	136.4 ± 1.7	kJ/mol	PAC	Morse, Parker, et al., 1989	solvent: Heptane; The reaction enthalpy relies on 0.72 for the quantum yield of CO dissociation
