← ScienceWhich mechanism decreases reaction time in catalytic converters?
A)Surface adsorption reduces activation energy✓
B)Increased pressure shifts equilibrium right
C)Elevated temperature lowers collision frequency
D)Reduced volume favors gaseous reactants
💡 Explanation
Surface adsorption of reactants onto the catalyst provides an alternate reaction pathway with a lower activation energy, thus the reaction accelerates because of preferential adsorption, which leads to faster conversion rather than a direct pressure or temperature effect.
