Individual Reactions
C5HO5Re (solution) = (solution) + C5O5Re (solution)
By formula: C5HO5Re (solution) = H (solution) + C5O5Re (solution)

ΔrH° | 74.7 ± 1.0 | kcal/mol | EChem | Parker, Handoo, et al., 1991 | solvent: Acetonitrile; Please also see Tilset and Parker, 1989. The reaction enthalpy was obtained from the pKa of the hydride complex (MH), 21.1, and from the oxidation potential of the anion (M-), Re(CO)5(-), by using the equation: ΔHrxn [kJ/mol] = 5.71pKa(MH) + 96.485(Eo)ox(M-) + C. C is a constant that was calculated as 59.49 kcal/mol Parker, Handoo, et al., 1991, by adjusting the previous equation to the calorimetrically derived values for the reactions Cr(Cp)(CO)3(H)(solution) = Cr(Cp)(CO)3(solution) + H(solution), 61.5 ± 1.0 kcal/mol, and Cr(Cp)(CO)2(PPh3)(H)(solution) = Cr(Cp)(CO)2(PPh3)(solution) + H(solution), 59.8 ± 1.0 kcal/mol Kiss, Zhang, et al., 1990. C depends on the solvent and on the reference electrode. The value given implies that the electrode potentials are referenced to ferrocene/ferricinium electrode |
