Assertion: Iron(III) catalyses the reaction between iodide and persulphate ions. Reason: Transition metals act as catalysts. (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

Catalytic activity of transition metals is due to their ability to adopt multiple oxidation states and form complexes. Iron

(III)

catalyses the reaction between iodide and persulphate ions.

2 I^{-} + S_{2} O_{B}^{2 -} \to I_{2} + 2 S O_{4}^{2 -}

This can be explained as :

2 F e^{3 +} + 2 F \to 2 F e^{2 +} + I_{2}

2 F e^{2 +} + S_{2} O_{8}^{2 -} \to 2 F e^{3 +} + 2 S O_{4}^{2 -}
