← ScienceWhich catalytic mechanism reduces pollutants in car catalytic converters?
A)Surface adsorption and intermediate formation✓
B)Enthalpy reduction during reverse reactions
C)Increasing reactant kinetic energy directly
D)Decreasing total system activation entropy
💡 Explanation
Surface adsorption and intermediate formation reduces pollution, because a catalyst provides an alternative reaction pathway with lower activation energy that depends on holding the transition compound at the surface; therefore, the reaction speeds faster, rather than lowering energy through increasing energy input or enthalpy.
