← ScienceWhich outcome reduces methanol yield after catalyst poisoning?
A)Decreased surface reaction rates✓
B)Increased equilibrium conversion
C)Enhanced catalyst active area
D)Improved heat transfer efficiency
💡 Explanation
Decreased methanol production occurs because the catalyst is poisoned with sulfur compounds blocking its active sites, thereby reducing the effective surface area available for the adsorption, the chemical transformation or 'surface reaction rates'. Therefore, reaction rate decreases rather than equilibrium conversion increasing because catalytic activity declined.
