← ScienceWhich mechanism causes a lower ignition temperature in catalytic converters?
A)Surface adsorption lowering activation energy✓
B)Increased reactant kinetic energy transfer
C)Decreased product chain termination rate
D)Enhanced convective heat transfer coefficient
💡 Explanation
Surface adsorption increases reactant concentration on the catalyst's surface, facilitating bond weakening, which provides an alternative reaction pathway; Catalysis thereby reduces the activation energy, so a converter rapidly reaches light-off, rather than relying solely on high temperatures.
