← ScienceWhich consequence results when irreversible catalyst poisoning occurs inside catalytic converters?
A)Reduced NOX to Nitrogen conversion✓
B)Increased catalyst surface area roughness
C)Enhanced carbon monoxide oxidation rate
D)Lower hydrocarbon combustion activation energy
💡 Explanation
Permanent catalyst poisoning obstructs active sites, impeding catalytic activity because irreversible adsorption blocks reaction pathways; therefore NOX reduction is diminished, rather than improved catalytic activity because adsorption alters selectivity under transient conditions.
