Chemistry: Catalysts Multiple Choice Question

AI Thread Summary
Catalysts speed up reaction rates primarily by decreasing the energy of activation and increasing collision frequency. Options B and E are confirmed as correct, while option C is also valid since catalysts change the reaction pathway. Option A is incorrect, as catalysts do not increase activation energy. The discussion emphasizes understanding the role of catalysts in altering reaction dynamics without affecting the equilibrium constant. Overall, the key points highlight the mechanisms by which catalysts enhance reaction rates.
