For a general redox reaction Anode Red_1 → Ox_1^n_1^+ + n_1 e^- Cathode O x_2+ n_2 e^- → Red_2^n_2- Which of the following statement is incorrect?
For a general redox reaction
Anode $\displaystyle \operatorname{Red}_1 \rightarrow \mathrm{Ox}_1^{\mathrm{n}_1^{+}}+\mathrm{n}_1 \mathrm{e}^{-}$
Cathode $\displaystyle \mathrm{O} x_2+\mathrm{n}_2 \mathrm{e}^{-} \rightarrow \operatorname{Red}_2{ }^{\mathrm{n}_2-}$
Which of the following statement is incorrect ?
Official answer
From NTA’s final answer key for this paper.
(4)
If the reaction is carried out reversibly, the electrical work done is equal to the ratio of charge and potential difference through which charge is moved.
