← ScienceWhich outcome results when a catalyst exceeds its temperature constant within an industrial reactor?
A)Surface area reduction by sintering✓
B)Reaction rate increase from activation energy
C)Equilibrium shift favoring reactants
D)Pressure decrease from gas dissolution
💡 Explanation
When a catalyst exceeds its temperature constant, sintering occurs because increased thermal energy allows surface atoms to migrate and form larger particles, reducing surface area and activity. Therefore, surface area reduction results, rather than increased rate, shifted equilibrium, or pressure decrease, which respond to different drivers.
