Comparison of KC, KO, SC/O parameters k25 and Ea resulting from the different methods
| Method | Temperature range (°C) | Parameter | k 25 (Pa) | E a (kJ mol−1) |
|---|---|---|---|---|
| Radiolabel | 10–35 | K C | 36 ± 2 | 63.09 ± 6.23 |
| MIMS | 10–40 | 34 ± 1 | 62.62 ± 3.44 | |
| Radiolabel | 15–35 | K O | 23 100 ± 3430 | 16.89 ± 2.59 |
| MIMS | 10–40 | 24 400 ± 701 | 17.01 ± 2.48 | |
| Radiolabel | 05–40 | S C/O | 2003 ± 22 | –28.66 ± 0.51 b |
| MIMS | 10–25 | 1814 ± 117 | –48.19 ± 4.17 a | |
| 25–40 | – | –30.51 ± 6.41 b |
No differences were observed in k25 between methods. No differences were observed in Ea values for KC and KO values between methods (ANOVA). Theletters next to the Ea values indicate significant differences for the SC/O values (Tukey HSD, P<0.05).
