After averaging the groups of curves corresponding to the same rotation rate (Fig. ), it can be insinuated that at an infinitely high rotation rate, 𝑔(𝜔) must be unity while tending towards zero at low rotation rates. It, however, cannot reach zero, as when the O2 dissociation is allowed to start at the beginning of the OCP period (Eq. 8), there is an initial amount of O2 in the direct vicinity of the electrode. To account for the latter, without the possession of an accurate mathematical model that would need to capture time-dependent convective and diffusive mass transport linked to a to-be-determined chemical reaction, the effective rotation rate 𝜔 ,** is introduced. 𝜔 ,** can be inferred from when the curves in Fig. lie on top of each other (Fig. ) as the lefthand site of Eq. 8b is independent of 𝜔 ,** . This allows the mass transport problem (𝑦(𝑥) = 𝑏 + 𝑠 • 𝑥, Eq. 8c) to be linearized, much like the Koutecký-Levich equation for steady-state mass transport problems in the determination of ORR activities. This linearization leads to the plot in Fig. and 2g from which the value 𝐹𝑘 • 𝑓(𝑄) for each coverage value can be obtained when extrapolating to 1 𝜔 ,** ⁄ = 0 (Eq. 8d) where the transport of O2 to the surface is instantaneous. Plotting this value against the corresponding O-upd charge, the plots in Fig. and 3b are obtained. From the log-scaled plot, a power law for 𝑓(𝑄) is deduced (Eq. 9a). Hence, the rate equation of the dissociation of molecular oxygen follows the rate equation in Eq. 9b corresponding to the chemical reaction in Eq. 9c.
