JEE Main 20266 Apr, Evening shiftChemistryEasyRedox Reactions and Electrochemistry138× since 2002For a general redox reaction, Anode: Red1→Ox1n1++n1e−\mathrm{Red_1}\to\mathrm{Ox_1^{n_1+}}+n_1e^-Red1→Ox1n1++n1e−; Cathode: Ox2+n2e−→Red2n2−\mathrm{Ox_2}+n_2e^-\to\mathrm{Red_2^{n_2-}}Ox2+n2e−→Red2n2−. Which of the following statement is incorrect ?AOption A. The overall reaction can be written as n2Red1+n1Ox2⇌n2Ox1n1++n1Red2n2−n_2\mathrm{Red_1}+n_1\mathrm{Ox_2}\rightleftharpoons n_2\mathrm{Ox_1^{n_1+}}+n_1\mathrm{Red_2^{n_2-}}n2Red1+n1Ox2⇌n2Ox1n1++n1Red2n2−BOption B. The electrons do not appear in the overall reaction because electrons produced at the anode are consumed at the cathode.COption C.

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.CheckStep-by-step hintSkip · show solution
