Which outcome results when a catalytic converter fails?

💡 Explanation

Increased hydrocarbon emissions exit because the catalytic converter's oxidation and reduction processes halt due to catalyst deactivation. The mechanism of failure involves catalyst poisoning; therefore uncombusted hydrocarbons pass through rather than being converted to CO2 and water.
