Despite the adequacy of a thermodynamic analysis in explaining the activity trends, it often provides an upper bound activity estimation. In this regard, an electrochemical kinetic model is designed for studying the kinetics of ORR, the details of which are provided in the supporting information (Text S1). We have computed the energy barriers for O-O bond dissociation steps for O2, *OOH, and H2O2 species via CI-NEB calculations, whereas an activation barrier of 0.25 eV has been adapted for electrochemical reactions in accordance with the report by Tripkovic et al. The kinetic limiting steps along the most energetically facile pathway for all the methods are identified (Table ), and the corresponding rate constants at the ORR working potential of 0.9 V is given in Figure . It can be seen that the activity trend predicted from kinetics is in agreement with thermodynamically predicted trends which corroborates the observation by Hansen et al. for Pt(111) surface. PBE, PBE-D2, RPBE-D2, and optPBE methods are occupying the higher most kinetic activiy region as observed in the thermodynamic investigation. However, it is to be noted that for PBE and rPW86 methods, there is a shift in thermodynamic and kinetic limiting steps from *O hydrogenation to *O2 hydrogenation and from *OH hydrogenation to *O2 hydrogenation, respectively. This suggests that potential dependent activation barrier investigation could be important in correctly identifying the steps determining the ORR kinetics. The selectivity between 4e -and 2e -oxygen reduction is analyzed by comparing the rates of *OOH→*O+H2O and *OOH →H2O2 steps as they govern the further pathways followed by **OOH (Figure ). Except for RPBE-D3, revPBE and rPW86, all other methods are found to possess a higher selectivity towards H2O formation compared to H2O2. It is to be noted that we have adapted a constant electrochemical barrier and hence therefore, not compared the predicted kinetics with the experiment as obtaining transition states of all elementary steps across all the methods considered is computationally expensive. Furthermore, it is reported that the entropic effect associated with proton mobility could result in different experimental frequency factors and hence kinetics. However, since thermochemical O-O bond dissociation steps can play a vital role in deciding the formation energetics of intermediates channeling ORR pathways, we have calculated the activation barriers associated with these steps across all the methods (Figure ). Our calculations revealed the least O2 dissociation barrier (0.08 eV) for the PBE-D3 method, which is 0.69 eV lesser than the PBE method, which implies the inclusion of dispersion interactions greatly affects the kinetics of ORR.
