Which outcome occurs when reactants struggle to access catalyst active sites?

💡 Explanation

The reaction rate becomes mass-transport or diffusion limited because insufficient reactants can reach the active sites; therefore the observable rate is not determined by the chemical kinetics, rather than true catalyst performance under ideal conditions.
