← ScienceWhich outcome arises when an inhibitor poisons catalysts?
A)Reaction pathways become kinetically blocked✓
B)Average excess enthalpy decreases rapidly
C)Equilibrium shifts unpredictably, oscillating
D)Catalyst surface area increases exponentially
💡 Explanation
Catalyst poisoning by an inhibitor causes the active sites to be blocked via chemisorption, therefore reaction pathways cannot proceed because they lack adsorption sites, rather than an issue of catalyst surface area alone.
