← ScienceWhich outcome increases the rate when nickel catalyzes ethene hydrogenation?
A)Increased reactant surface area exposure✓
B)Elevated overall system pressure
C)Reduced average gas kinetic vibration
D)Increased catalyst particle aggregation
💡 Explanation
Increased nickel surface allows more ethene adsorption because the mechanism limiting the reaction is typically surface reaction. Therefore, greater surface contact raises the reaction’s rate rather than increased pressure's nonspecific effect or reduced vibrations lowering the reaction rate.
