Which consequence increases when catalyst poisoning reduces surface adsorption?

A)Reaction rate decreases significantly
B)Activation energy barrier reduces
C)Equilibrium constant increases tenfold
D)Pre-exponential factor increases drastically

💡 Explanation

A lower concentration of adsorbed reactants decreases the reaction rate because the **adsorption-desorption mechanism** requires frequent binding. Therefore, the overall reaction slows, rather than activation energy reductions which would require a different change to proceed more efficiently.
