← ScienceWhich consequence results when catalytic converter overheating disrupts the chemical equilibrium?
A)Increased hydrocarbon and CO emissions✓
B)Increased nitrogen oxides reduction fraction
C)Increased exhaust gas oxygen concentration
D)Decreased catalyst bed thermal conductance
💡 Explanation
Increased temperature favors the reverse reactions due to Le Chatelier's principle, favoring increased hydrocarbon rather than maximized conversion, because high temperatures make oxidation reactions less favorable. Therefore, hydrocarbon and CO emissions increase, rather than the converter properly functioning.
