Which outcome occurs when a non-ideal catalyst contaminates a chemical reactor?

💡 Explanation

Reaction selectivity degrades because catalyst poisoning reduces available surface area affecting activated complex orientations leading to unwanted side reactions, therefore, undesired products form at an accelerated rate rather than desired; poisoned byproducts are thermodynamically less favorable.
