Which consequence results in industrial ammonia synthesis when catalyst surface area diminishes?

A)Equilibrium shifts towards reactants
B)Reaction rate decreases drastically
C)Activation energy gets lowered slightly
D)Equilibrium constant also changes

💡 Explanation

A smaller catalyst surface area reduces the frequency of reactant adsorption and subsequent surface reactions due to decreased active sites; therefore, the overall reaction rate decreases drastically, rather than a major shift in equilibrium, because equilibrium depends primarily on thermodynamics.
