← ScienceWhich 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.
