The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states that "Iron(III) catalyzes the reaction between iodide and persulphate ions." - **Explanation**: Iron(III) ions (Fe³⁺) can act as a catalyst in the reaction between iodide ions (I⁻) and persulphate ions (S₂O₈²⁻). The reaction can be represented as: \[ 2 I^- + S_2O_8^{2-} \rightarrow I_2 + 2 SO_4^{2-} \] In this reaction, Fe³⁺ ions facilitate the conversion of iodide ions to iodine (I₂) and persulphate ions to sulfate ions (SO₄²⁻). ### Step 2: Analyze the Reason The reason states that "Transition metals act as catalysts." - **Explanation**: Transition metals, including iron, are known for their ability to act as catalysts in various chemical reactions. This is primarily due to their ability to adopt multiple oxidation states and form complexes, which allows them to facilitate reactions without being consumed in the process. ### Step 3: Determine the Relationship Now we need to determine if the reason correctly explains the assertion. - **Conclusion**: While both the assertion and the reason are true, the reason does not specifically explain why Iron(III) acts as a catalyst in the reaction between iodide and persulphate ions. The assertion focuses on a specific reaction, whereas the reason provides a general property of transition metals. ### Final Answer Therefore, the correct conclusion is: - The assertion is true. - The reason is true, but it does not provide a correct explanation for the assertion. Thus, the answer is: **Assertion is true, Reason is true, but Reason is not the correct explanation of Assertion.** ---
