The extent of conversion at oscillatory steady state of the considered system of Figure was evaluated as a function of applied square wave frequency f, waveform amplitude, and waveform amplitude position. As depicted in Figure at 150 °C, dynamic oscillation of the surface binding energy of B at a fixed amplitude can occur over a range of oscillation endpoints. The position of the strong binding energy of B endpoint was the independent variable in the heat maps of Figures 12D (ΔU A ~ 0.5 eV), 12E (ΔU A ~ 1.0 eV), and 12F (ΔU A ~ 1.5 eV), where the oscillatory steady state TOF B was determined via simulation.
