Which risk increases when an automotive catalytic converter reaches end-of-life?

A)Increased atmospheric nitrous oxide emissions
B)Decreased unburned hydrocarbon combustion
C)Lean misfires within engine cylinders
D)Premature degradation tolambda oxygen sensors

💡 Explanation

Increased atmospheric nitrous oxide emissions occur, because catalyst deactivation inhibits redox reactions (Reductants Oxidation), therefore N₂ formation diminishes rather than N₂O, since the metal active sites are poisoned.
