The correct Answer is:
To solve the question regarding the effect of acetamide on the decomposition of hydrogen peroxide, we will analyze the options provided and determine which one correctly describes the role of acetamide in this reaction. ### Step-by-Step Solution: 1. **Understanding the Reaction**: - The decomposition of hydrogen peroxide (H₂O₂) can be represented by the equation: \[ 2 H₂O₂ \rightarrow 2 H₂O + O₂ \] - This reaction can occur spontaneously, but its rate can be influenced by various substances. 2. **Analyzing the Role of Acetamide**: - Acetamide is added to the reaction to slow down the decomposition of hydrogen peroxide. We need to identify what this means in terms of chemical terminology. 3. **Evaluating the Options**: - **Option 1: Detainer** - This term refers to the action of withholding or delaying something. It does not specifically relate to chemical reactions, so this option is incorrect. - **Option 2: Stopper** - A stopper is a physical object used to seal containers. It does not apply to the context of chemical reactions, making this option incorrect as well. - **Option 3: Promoter** - A promoter is a substance that enhances the effectiveness of a catalyst but does not have a catalytic effect itself. Since acetamide slows down the reaction rather than promoting it, this option is also incorrect. - **Option 4: Inhibitor** - An inhibitor is a substance that decreases the rate of a chemical reaction or prevents it from occurring. Since acetamide slows down the decomposition of hydrogen peroxide, this option is correct. 4. **Conclusion**: - Based on the analysis, acetamide acts as an **inhibitor** in the decomposition of hydrogen peroxide. ### Final Answer: Acetamide acts as an **inhibitor** in the decomposition of hydrogen peroxide.
