Question

which statement about inhibitors is true? inhibitors only work at high temperatures. inhibitors always change states of matter during the reaction. inhibitors slow down the rate of reaction. inhibitors result in a lower activation energy for the reaction.

Explanation:

• Analyze each option:
• "Inhibitors only work at high temperatures": Inhibitors can function at various temperatures, not just high ones.
• "Inhibitors always change states of matter during the reaction": Inhibitors don't necessarily change states of matter; their role is to affect reaction rate.
• "Inhibitors slow down the rate of reaction": By definition, inhibitors (like negative catalysts) decrease the rate of a chemical reaction.
• "Inhibitors result in a lower activation energy for the reaction": Inhibitors increase activation energy (or slow reaction by other means), while catalysts lower it.

Answer:

Inhibitors slow down the rate of reaction.
