| Abstract: | O?2 radicals were formed in the presence of 2,5- dimethyl benzoquinone (DMBQ). The equilibrium constant of the electron transfer reaction DMBQ + O?2 ? DMBQ? + O2 was determined. From this value and from E0(DMBQ/DMBQ?) we calculated the redox potential of the couple O2/O?2, as E0 (O2/O?2) = ?0.33 V. |
