Which outcome results when an oxidation catalyst in a catalytic converter degrades?

💡 Explanation

Degradation reduces the catalyst surface area, slowing down the catalytic oxidation process. The mechanism is decreased heterogeneous catalysis efficiency because fewer reactant molecules are adsorbed and converted. Therefore, hydrocarbon conversion decreases, rather than altering nitrogen or CO dynamics.
