Which outcome occurs when atmospheric CO oxidation catalyst deactivates?

💡 Explanation

A deactivated catalyst lowers the active surface area sites accelerating the reaction via surface adsorption mechanism and lowering the reaction pathway’s activation energy of CO oxidation. Therefore, the reaction rate decreases because fewer CO molecules react per unit time, rather than increased area roughness as the deactivation happens gradually.
