Fig. 5

The plot of the reaction rate as a function of \(\gamma\) when \(\delta =1\). In this case, the reaction rates \(R_{{\rm A}}\) and \(R_{{{\rm B}}}\) are observed to be equivalent. For small \(\gamma\), the rate is independent of \(\gamma\) and is only dependent on k and K, indicating that it is surface-controlled. However, for large \(\gamma\), the rate depends on k, K, and D, indicating a combined surface reaction and diffusion control (see text)
