The data table of GWB database has some logK data for significant reactions. In these data block the reaction between O2 and e- exists.

* log k for eh reaction

-91.0454 -83.1028 -74.0521 -65.8632

-57.8929 -51.6850 -46.7266 -42.6842

I would like to know this reaction indicates whether

2H2O = O2(aq) + 4H+ + 4e-

or

2H2O = O2(g) + 4H+ + 4e-.

As far as I know, it is the reaction with O2(g).
