Which outcome occurs when a catalytic converter ages?

💡 Explanation

Lower oxidation occurs, because catalyst effectiveness declines with age. This is due to catalyst poisoning. The activation energy increases as the active sites are blocked; therefore the reaction rate and conversion efficiency drops rather than it performing optimally or improving catalytic activity.
