← ScienceIn catalytic converters restricted by carbon buildup, which effect reduces efficiency?
A)Increased activation energy requirement✓
B)Decreased equilibrium product formation
C)Favored reactant adsorption kinetics
D)Enhanced surface area utilization
💡 Explanation
Carbon reduces active catalytic sites, influencing reaction kinetics; blockage increases the activation energy necessary for reactant conversion, because the required surface interactions are diminished. Thus, higher activation energy decreases overall efficiency, rather than promoting the catalytic process.
