← ScienceWhich consequence results when exceeding the catalyst saturation point in catalytic converters?
A)Reaction rate reaches maximum, then plateaus✓
B)Increased NOX conversion above equilibrium potential
C)Enhanced catalyst surface area performance gain
D)Decreased poisoning effect, extending catalyst life
💡 Explanation
Reaction rate plateaus because further increases in reactant concentration cannot increase binding to available active sites on the catalyst surface; therefore, the reaction rate is limited, rather than exhibiting a linear increase.
