For a general redox reaction Anode : Red ₁ Ox ₁^ n₁^+ + n₁ e^- Cathode : Ox ₂ + n₂ e^- Red ₂^ n₂^- Which of the following statements is incorrect?

Options

  1. AThe overall reaction can be written as n₂ Red ₁ + n₁ Ox ₂ n₂ Ox ₁^ n₁^+ + n₁ Red ₂^ n₂^-
  2. BThe electrons do not appear in the overall reaction because electrons produced at the anode are consumed at th
  3. CIf the reaction is carried out reversibly, the electrical work done is equal to the ratio of charge and potent

Correct answer

3

Step-by-step solution

For the given redox reaction, the half-cell reactions are: Anode: Red ₁ Ox ₁^ n₁^+ + n₁ e^- Cathode: Ox ₂ + n₂ e^- Red ₂^ n₂^- To obtain the overall balanced chemical equation, we multiply the anode reaction by n₂ and the cathode reaction by n₁ so that the number of electrons lost equals the number of electrons gained: n₂ Red ₁ n₂ Ox ₁^ n₁^+ + n₁ n₂ e^- n₁ Ox ₂ + n₁ n₂ e^- n₁ Red ₂^ n₂^- Adding these gives the overall reaction: n₂ Red ₁ + n₁ Ox ₂ n₂ Ox ₁^ n₁^+ + n₁ Red ₂^ n₂^- Thus, statement (A) is correct.
