← ScienceIn a catalytic converter, which outcome sharply reduces pollutant oxides?
A)Increased surface reaction equilibrium✓
B)Reduced catalyst thermal expansion
C)Enhanced mechanical compression strength
D)Decreased substrate vibrational frequency
💡 Explanation
Increased surface reaction equilibrium occurs because the precious metal catalyst lowers the activation energy for redox reactions via surface adsorption, therefore converting NOx to harmless gases, rather than only enabling decomposition reactions at high temperatures without catalysts.
