Which outcome occurs within a catalytic converter when the exhaust temperature exceeds maximum operating temperature?

💡 Explanation

When exhaust temperature exceeds design limits, catalyst sintering and support material phase changes occur because increased thermal energy drives chemical decomposition, reducing the surface area. Therefore thermal decomposition leads to poisoning, rather than increased efficiency, reduced back pressure, or improved air-fuel mixtures, which require different mechanisms.
