Vedclass · Answer

(D) The catalytic reaction proceeds in two steps:$1$. $2 Fe^{3+} + 2 I^{-} \longrightarrow 2 Fe^{2+} + I_2$$2$. $2 Fe^{2+} + S_2 O_8^{2-} \longrightarrow 2 Fe^{3+} + 2 SO_4^{2-}$In the first step,$Fe^{3+}$ oxidises the iodide ion $(I^-)$ to iodine $(I_2)$ and is reduced to $Fe^{2+}$.In the second step,$Fe^{2+}$ reduces the persulphate ion $(S_2 O_8^{2-})$ to sulphate $(SO_4^{2-})$ and is oxidised back to $Fe^{3+}$.Thus,statements $A$ and $D$ are correct.
