The physical restriction of non-repulsive surfaces for adsorption alters the enthalpy of the surface reaction and the surface transition state energy by association. The implication is apparent in the TOF B heat map of Figure , where the TOF B for the surface reaction elementary step is presented (color) as a function of the surface coverage of A (θ A ) and the relative binding energy of B [eV]. At low relative binding energies of B, the system exhibits a gradual change in the TOF B before a sharp transition above -0.7 eV; this transition is the condition where the binding energy of A approaches zero. Figure also reveals part of the origin for fast dynamic TOF B ; at high surface coverage of A, the surface reaction can achieve TOF B of ~10 2 s -1 . These unique behaviors indicate that three-order-of-magnitude enhancement in rate is achievable for low gamma systems, but selection of the dynamic oscillation of surface binding energies must be carefully selected unique to each system.
