Reaction rate coefficients for the sphere model predicted by SMPNP model with different substrate sizes. p3b is the substrate bulk density. (a) Substrate alone is diffusive and all particles are electrically neutral. (b) Counterion and coion sizes are 3.0 Å, and ionic strength is 150 mM in all SMPNP calculations.
