← ScienceWhich risk increases when designing an industrial catalytic reactor for high throughput?
A)Mass transport limitations become rate-limiting.✓
B)Catalyst poisoning becomes thermodynamically favored.
C)Equilibrium shifts towards reactant generation.
D)The reactor becomes endothermic by design.
💡 Explanation
If mass transport significantly slows down the reaction kinetics at higher throughput then mass transport limitations become rate-limiting, thereby impeding efficient catalysis, because the reactants cannot reach the active sites quickly enough; therefore, high rates impact equilibrium rather than thermodynamic favorability.
