← ScienceWhich outcome primarily dictates the reaction rate in heterogeneous catalysis within a packed bed reactor?
A)Surface reaction kinetics of reactants✓
B)Bulk diffusion of reactants in pores
C)External mass transfer to catalyst
D)Internal heat transfer within catalyst
💡 Explanation
In heterogeneous catalysis, the surface reaction kinetics becomes rate-determining when diffusion limitations are minimized, due to the availability of reactants at the active catalyst sites, thus dictating the reaction rate. Therefore, reaction kinetics influence reactor output rate rather than diffusion or transfer processes limiting it, under specific conditions.
