Which outcome occurs when reactor catalysts degrade unexpectedly?

💡 Explanation

Degraded catalyst lowers active surface area; the *rate of reaction* decreases because fewer molecules react with the catalyst per unit time. Therefore, yield drops rather than increasing downstream load or selectivity because the mass action is limited.
