← ScienceWhich mechanism accelerates oxygen production rate in catalytic converters?
A)Increased surface adsorption of reactants✓
B)Reduced activation energy requirement
C)Enhanced product desorption kinetics
D)Decreased equilibrium constant magnitude
💡 Explanation
Increased surface adsorption creates more active sites, accelerating surface reactions via the Langmuir-Hinshelwood mechanism because a higher reactant concentration resides on the catalyst surface. Therefore, reaction rate increases, rather than being limited by activation energy or thermodynamic equilibrium.
