Which outcome occurs when an automotive catalytic converter's inlet temperature oscillates rapidly?

💡 Explanation

Reduced light-off occurs because thermal cycling hinders the Langmuir-Hinshelwood mechanism by intermittently cooling the catalyst surface below its activation temperature. Therefore, conversion efficiency drops, rather than optimizing combustion, which would require stable operation.
