Which risk increases when a catalytic converter experiences thermal runaway?

💡 Explanation

Increased temperature accelerates unwanted reactions because the Arrhenius equation dictates that reaction rate increases exponentially with temperature during thermal runaway. Therefore, NOx production rises rather than catalyst oxidation, which inhibits desired reactions, or efficient hydrocarbon conversion under normal controlled temperatures.
