It's an ORR reaction. @mjohnson541 for posterity, could you share a bit of details on what the system actually is? We usually share a few details in the introduction.

This is a microkinetic model for the net electrochemical reaction O2 + 4 H+ + 4e- -> 2 H2O on platinum at 0.9 volts relative to the standard hydrogen electrode with 9 integrated species and 19 reactions.
