← ScienceWhich outcome occurs when the activation energy of a catalytic converter within an automobile exhaust system degrades?
A)Reduced pollutant conversion reaction rate✓
B)Increased engine combustion energy output
C)Enhanced catalyst surface entropy effects
D)Elevated exhaust temperature homogeneity profile
💡 Explanation
Reduced catalyst health increases the activation energy needed; therefore, diminishing catalytic activity lowers the pollutant conversion reaction rate because precious metal surface interactions decrease, rather than exhaust modifications or entropy dominating the reaction.
