The correct Answer is:
To solve the question regarding the decomposition of hydrogen peroxide (H₂O₂) and what retards this reaction, we can follow these steps: ### Step 1: Understand the Reaction The decomposition of hydrogen peroxide can be represented by the following chemical equation: \[ 2H_2O_2 (l) \rightarrow 2H_2O (l) + O_2 (g) \] ### Step 2: Identify the Inhibitors Inhibitors are substances that slow down or prevent chemical reactions. In the context of the decomposition of H₂O₂, we need to identify which of the given options acts as an inhibitor. ### Step 3: Analyze the Options The options provided are: 1. Acetylilide 2. M1O2 3. Zn (Zinc) 4. Colloidal 5. Nickel ### Step 4: Determine the Correct Answer Among the options, acetylilide is known to act as an inhibitor for the decomposition of hydrogen peroxide. It slows down the reaction by preventing the breakdown of H₂O₂ into water and oxygen. ### Step 5: Conclusion Thus, the correct answer to the question is: **Acetylilide** is the substance that retards the decomposition of hydrogen peroxide.
