[2025-10-01T02:18:34.384890] [PI reasoning] **Answering MCQ about catalysts**

I need to respond to the multiple-choice question about the material that speeds up chemical reactions without becoming involved. The standard answer is "catalyst," and the corresponding letter is C. I should also include an in-text citation, possibly from a textbook. I think I’ll quickly look up a definition of "catalyst" to ensure everything is accurate and provide the necessary support for my answer.
