Which outcome occurs when an industrial catalyst's surface area decreases during exothermic reaction processing?

A)Reaction rate decreases noticeably
B)Equilibrium shifts substantially right
C)Activation energy requirement lowers
D)Selectivity for products increases

💡 Explanation

When surface area reduces during catalysis, effective concentration decreases, therefore the reaction rate will decrease noticeably. This occurs because fewer reactant molecules can interact with the active surface, rather than equilibrium shifts or activation energy reduction.
