Which outcome primarily governs steady-state conversion in a catalytic reactor when space velocity significantly increases?

💡 Explanation

When space velocity increases significantly, the residence time of reactants inside a catalytic reactor decreases, enhancing intraparticle diffusion limitations because reactants are unable to diffuse into the core of the catalyst pores before exiting. Therefore, intraparticle diffusion intensifies, rather than shifting rate-determining steps, loss of equilibrium, or reactant poisoning, which result from different conditions.
