Figure shows the efficiency of the applied waveforms as a function of imposed amplitude at a constant frequency of 10 Hz. Initially, near zero amplitude, the efficiency is low for all waveforms as shown by the shallow slope of the plot. Once the oscillation amplitude achieves 10-20 kJ mol -1 (i.e. 0.1-0.2 eV), the relationship between ΔΔG and ΔU is effectively described by a straight line. The slope of this line is the system efficiency during dynamic catalysis since it is the ratio of two energy units. The maximum efficiency observed was ~40 % for the square wave with the sinusoidal and triangular wave being slightly less effective at 34% and 30%, respectively.
