← ScienceWhich mechanism enhances reaction velocity in catalytic converters?
A)Surface adsorption reduces activation energy✓
B)Le Chatelier's principle shifts equilibrium
C)Homogeneous mixing raises reactant concentration
D)Increased temperature reduces internal resistance
💡 Explanation
In catalytic converters, surface adsorption increases reaction velocity because gaseous reactants bind to the catalyst's surface and weaken existing bonds. This lowers the activation energy for bond cleavage. Therefore, reactions proceed more rapidly rather than being equilibrium shifts or reduced resistance.
