Science

Which outcome occurs when a novel catalyst increases the *pre-exponential factor* disproportionately relative to lowering _activation energy_ in catalytic converters?

A)Equilibrium shifts toward CO₂ formation
B)Reaction order becomes zero-order
C)Active site poisoning risk increases
D)Mass transport limitations are amplified

💡 Explanation

Mass transport becomes limiting because increased reactivity caused by Arrhenius equation changes, increases the reaction rate beyond substrate diffusion in heterogeneous catalysis; therefore, mass transport, rather than kinetics controls reaction rates, rather than other factors.
