Which outcome sharply limits catalytic activity inside a fuel reformer?

💡 Explanation

Catalyst activity plummets due to catalyst surface poisoning because strong chemical adsorption blocks active sites on the catalyst; therefore reaction rate drops significantly, rather than activity increasing, because other side-reactions become dominant when the primary surface is blocked.
