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

A)Increased catalyst poisoning probability
B)Reaction selectivity becomes stable
C)The equilibrium constant increases slightly
D)Activation energy magnitude will drop

💡 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.
