The turnover frequency (TOF), as well as the reaction kinetics of ammonia synthesis, has been solved by microkinetic modeling (MKM) with CatMAP code.35 The reaction rate for each elementary step can be expressed as

where ri are the rates, kif/r are the forward/reverse rate constants, θim/in are the coverage of the surface species m/n, and pim/in are the pressure of the gas-phase reactants and products m/n for each elementary reaction step i.

The details and derivations of the calculations can be found in the Supporting Information.
