Which effect results when a catalytic converter in an automobile exhaust system loses its surface area?

A)Increased production of nitrogen oxides
B)Reduced engine compression ratio
C)Decreased fuel injection pressure
D)Elevated engine coolant temperature

💡 Explanation

When a catalytic converter loses surface area, the reaction rate decreases because fewer active sites are available for the catalyst mediated reactions, resulting in incomplete oxidation of hydrocarbons forming additional nitrogen oxides. Therefore increased nitrogen oxides result, rather than compression, fuel pressure, or coolant changes which operate under different mechanical failures.
