Which effect increases when the Arrhenius equation predicts an exponentially higher reaction rate when nickel catalyst particle size decreases?

A)Surface area to volume increases
B)Catalyst poisoning becomes non-selective
C)Activation energy barrier is overcome
D)Reactant molecule solvation entropy drops

💡 Explanation

Increased nickel catalyst reaction rates occur via surface adsorption, and therefore smaller catalyst particles provide increased active sites and lower effective activation energy for reactants. This is because surface area increases, rather than increased catalyst poisoning or solvation changes.
