Using the standard electrode potentials from Table 7.1, predict if the reaction Fe³⁺(aq) + I⁻(aq) is

Q: What is the correct answer for NCERT11?

The correct answer is B. For a reaction to be feasible, the oxidizing agent must be stronger than the reducing agent. The relevant half-reactions are: Fe³⁺ + e⁻ → Fe²⁺ (E° = +0.77 V) and I₂ + 2e⁻ → 2I⁻ (E° = +0.54 V). In the given reaction, Fe³⁺ acts as the oxidizing agent and I⁻ as the reducing agent. The reduction potential of Fe³⁺/Fe²⁺ (+0.77 V) is higher than that of I₂/I⁻ (+0.54 V), meaning Fe³⁺ is a stronger oxidizi

For a reaction to be feasible, the oxidizing agent must be stronger than the reducing agent. The relevant half-reactions are: Fe³⁺ + e⁻ → Fe²⁺ (E° = +0.77 V) and I₂ + 2e⁻ → 2I⁻ (E° = +0.54 V). In the given reaction, Fe³⁺ acts as the oxidizing agent and I⁻ as the reducing agent. The reduction potential of Fe³⁺/Fe²⁺ (+0.77 V) is higher than that of I₂/I⁻ (+0.54 V), meaning Fe³⁺ is a stronger oxidizing agent than I₂. Conversely, I⁻ is a stronger reducing agent than Fe²⁺. Therefore, Fe³⁺ will oxidize I⁻, and the reaction is feasible.
