Which consequence results when an industrial catalyst degrades during exothermal synthesis?

💡 Explanation

Runaway occurs because declining catalyst activity raises the required temperature to maintain the desired reaction rate, resulting in increased unreacted material and sharply escalated exothermal heat release; thus, safety diminishes rather than any composition shifts alone.
