Which mechanism limits catalytic converter efficiency as internal temperature decreases during vehicle idling?

💡 Explanation

When the catalytic converter temperature decreases, the reaction rates on its catalyst surface slow down because reaction rate exponentially increases with temp via the Arrhenius equation, reducing its primary function. Therefore decreased surface reaction rate occurs, rather than catalyst poisoning, diminished oxygen storage, or thermal degradation, which depend on additional factors.
