Which outcome occurs when a catalytic converter cools?

💡 Explanation

Reduced NOx conversion efficiency happens because decreased temperature hinders the catalytic activation process by reducing surface adsorption, therefore the reaction slows; rather than increasing other oxidation or metal surface area, temperature must be maintained.
