Science

Which consequence results when a positive catalyst's surface area is diminished during ethylene polymerization reactions?

A)Reduced overall reaction rate
B)Increased initiation event rate
C)Selective polymer branching increases
D)Higher molecular weight polymer formed

💡 Explanation

A smaller surface area reduces the binding sites available for ethylene monomers, decreasing access to active sites, therefore the reaction rate decreases, rather than accelerating, due to surface adsorption limitations hindering efficient collisions on catalysts.
