Which effect on equilibrium occurs when catalytic converters degrade?

A)Nitrogen oxides production rate increases
B)Carbon monoxide equilibrium quickly reduces
C)Hydrocarbon conversion approaches completion
D)Particulate matter gets completely eliminated

💡 Explanation

Increased nitrogen oxides occur in exhaust because catalyst degradation reduces the surface area available for the forward and reverse reactions enabling equilibrium. Therefore, the NO production increases rather than CO reduction given the limited catalyst capacity under higher operating temperatures.
