Which outcome results when sustained ignition failure occurs within catalytic converters?

A)Catalyst overheating and thermal runaway
B)Increased nitrogen oxide formation efficiency
C)Decreased carbon monoxide reaction rate
D)Enhanced platinum particle surface area

💡 Explanation

Reduced heat dissipation causes catalyst overheating and eventual thermal runaway of exothermic reactions because runaway accelerates exponentially with temperature due to the Arrhenius equation; therefore, thermal runaway happens rather than reactions slowing, because a large active surface area lowers activation energy.
