← ScienceWhich risk increases when surface treatment of a catalyst is flawed?
A)Reaction rate decreases significantly✓
B)Equilibrium constant shifts unfavorably
C)Activation energy increases dramatically
D)Pressure drop across reactor increases
💡 Explanation
Reaction rate decreases because catalyst surface area determines the number of active sites where reactions occur, and flawed treatment inhibits adsorption; therefore, fewer reactants adsorb and fewer conversion events happen, lowering the reaction rate, rather than affecting the equilibrium itself or the pressure only.
