Individual Reactions
Quantity | Value | Units | Method | Reference | Comment |
---|---|---|---|---|---|
ΔrH° | 1522. ± 6.3 | kJ/mol | D-EA | Ervin and Lineberger, 2005 | gas phase; High level calcns( Curtiss, Raghavachari, et al., 1991, Ricca and Bauschlicher, 1998) give DH ca. 84 |
ΔrH° | 1551. ± 8.8 | kJ/mol | G+TS | Bartmess, Scott, et al., 1979 | gas phase; The D-EA cycle does not close by 7 kcal/mol. The reason for this discrepancy is not known; value altered from reference due to change in acidity scale |
ΔrH° | 1524. ± 19. | kJ/mol | EIAE | Halmann and Platzner, 1969 | gas phase |
ΔrH° | <1534. ± 19. | kJ/mol | EIAE | Ebinghaus, Kraus, et al., 1964 | gas phase |
ΔrH° | 1529.7 | kJ/mol | N/A | Check, Faust, et al., 2001 | gas phase; MnF5-(q); ; ΔS(EA)=2.9 |
Quantity | Value | Units | Method | Reference | Comment |
ΔrG° | 1491. ± 6.7 | kJ/mol | H-TS | Ervin and Lineberger, 2005 | gas phase; High level calcns( Curtiss, Raghavachari, et al., 1991, Ricca and Bauschlicher, 1998) give DH ca. 84 |
ΔrG° | 1520. ± 8.4 | kJ/mol | IMRE | Bartmess, Scott, et al., 1979 | gas phase; The D-EA cycle does not close by 7 kcal/mol. The reason for this discrepancy is not known; value altered from reference due to change in acidity scale |
ΔrG° | 1500.8 | kJ/mol | N/A | Check, Faust, et al., 2001 | gas phase; MnF5-(q); ; ΔS(EA)=2.9 |
