← ScienceWhich outcome results when catalyst particles aggregate ex-situ?
A)Reduced active site surface area✓
B)Increased total reaction enthalpy
C)Stabilized intermediate compound formation
D)Enhanced product selectivity overall boost
💡 Explanation
Agglomeration reduces catalytic activity because it decreases the catalyst's available surface area via the mechanism of Ostwald ripening; therefore, fewer reactant molecules can interact. Since fewer active sites limits conversion, rather than enthalpy changes dominating the reaction.
