Which event causes catalyst poisoning to decrease reaction velocity?

💡 Explanation

Catalyst poisoning diminishes reaction rates because active site blocking prevents reactant adsorption; this is through competitive inhibition rather than temperature effects or equilibrium concentrations. Therefore only active site binding directly explains catalytic function decline.
