Dynamic diffusion and reaction in a porous solid catalyst layer
The overall reaction is A ⇀ B and is far from equilibrium under conditions here. Reactant A adsorbs reversibly over catalyst surface sites S: A + S ⇌ AS. Select Model 1 or 2, then click the Run button below. Click outside of input fields after changing values.
Select the "slow" rate determining step below: Model 1 (simple) or 2 (self-inhibiting).
