Which risk increases when catalytic converters operate below their minimum temperature threshold in automotive exhaust systems?

A)Reduced hydrocarbon conversion efficiency
B)Increased catalyst surface area growth
C)Decreased selectivity for CO2
D)Enhanced precious metal particle sintering

💡 Explanation

Reduced hydrocarbon conversion efficiency results if insufficient thermal energy is present because the activation energy requirement is not met, impairing the reaction rate. Therefore, lower thermal energy reduces catalytic activity, rather than increasing sintering or altering surface area effects.
