Which consequence primarily results when an industrial catalyst degrades?

💡 Explanation

Decreased performance occurs because catalyst degradation reduces the active surface area, thus diminishing overall reaction rate due to fewer reactant interactions via slower adsorption; therefore, lower rate results when active sites decline, rather than equilibrium changing or purity increasing.
