← ScienceWhich outcome occurs when increasing temperature significantly above the Arrhenius constant during catalyzed reaction?
A)Catalyst bed sintering accelerates rapidly✓
B)Reaction activation energy decreases dramatically
C)Surface area scales linearly faster
D)Rate constant deviates predictably downward
💡 Explanation
Catalyst bed sintering accelerates rapidly because higher thermal energy promotes atomic diffusion, surpassing activation energy; therefore, surfaces agglomerate, diminishing the active area, rather than a uniform scaling pattern, because extreme heat changes kinetic pathway.
