Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Iron(III) catalyzes the reaction by providing an alternative pathway with a lower activation energy. In this reaction, \( {Fe}^{3+} \) helps in the oxidation of iodide ions, accelerating the production of iodine and sulfate ions.
