Which consequence during platinum catalytic converter light-off phase results due to insufficient temperature?

A)Reduced CO oxidation efficiency
B)Increased NOₓ reduction effectiveness
C)Enhanced HC adsorption onto surface
D)Greater SO₂ byproduct formation

💡 Explanation

Insufficient temperature retards the rate of CO oxidation and HC oxidation. The Arrhenius equation dictates the reaction rate depends exponentially on temperature; therefore, CO oxidation is limited, rather than nitrogen oxide reduction which requires already high optimal temperatures.
