Which outcome occurs when a catalytic converter's rhodium component degrades?

💡 Explanation

Increased NOx emissions result because catalyst degradation reduces *surface area*. This lowers the accessibility of active sites, decreasing reaction rate, therefore, fewer NOx molecules are converted to N2 and O2, rather than efficiently reducing the input emissions.
