Which outcome increases risk when an oxidation catalyst degrades?

💡 Explanation

Increased risk of a runaway reaction exothermic rate results when the catalyst degrades because increased surface area might be exposed, increasing reaction rates dramatically via surface catalysis, rather than decreasing rates as one might expect.
