← ScienceWhich outcome results when a biofuel production catalyst degrades?
A)Reaction rate decreases drastically✓
B)Equilibrium shifts to more products
C)Biofuel's energy density increases
D)Feedstock conversion becomes exothermic
💡 Explanation
The reaction rate decreases significantly because catalyst *poisoning* reduces available active sites slowing down the bioreaction; therefore slower conversion, rather than equilibrium disruption or exothermicity, is the primary consequence.
