Individual Reactions
C5F12NO4S2- + = C5HF12NO4S2
By formula: C5F12NO4S2- + H+ = C5HF12NO4S2
| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔrG° | 1202. ± 8.4 | kJ/mol | IMRE | Koppel, Taft, et al., 1994 | gas phase; Per Leito, Raamat, et al., 2009, dGacid is likely too weak by at least 5.3 kcal/mol, due to problems in the ladder at dGacid=293 and 299. |
