Which consequence increases when an oxidation catalyst's support weakens?

💡 Explanation

Catalyst support weakening exposes more active sites to potential contaminants; this introduces a higher likelihood of catalyst poisoning because contaminant molecules adsorb and block active surface sites, therefore activity is reduced, rather than increased reaction rates or a change in constant.
