Catalysts are not “used up” in chemical reactions.Group of answer choicesTrueFalse

The statement "Catalysts are not 'used up' in chemical reactions" is True.

Explanation:

Catalysts are substances that increase the rate of a chemical reaction without undergoing any permanent chemical change themselves. They work by providing an alternative pathway for the reaction with a lower activation energy. Throughout the reaction, catalysts facilitate the transformation of reactants into products, but at the end of the reaction, they remain unchanged and can continue to catalyze more reactions.

This quality distinguishes catalysts from reactants, which are consumed in the reaction.

In summary, catalysts play a critical role in various chemical processes, including those in industrial production and biological systems (e.g., enzymes in biological reactions), while remaining intact after the reaction, allowing them to be reused multiple times.
