Mark the correct Nernst equation for the given cell. `F_((s))|Fe^(2+)(0.001 M) ||H^(+)(1M) | H_(2(g)) ( 1 bar ) | Pt_((s))` isA. `E_"cell"=E_"cell"^@-"0.591"/2 "log" ([Fe^(2+)][H^+]^2)/([Fe][H_2])`B. `E_"cell"=E_"cell"^@-"0.591"/2 "log" ([Fe][H^+]^2)/([Fe^(2+)][H_2])`C. `E_"cell"=E_"cell"^@-"0.0591"/2 "log" ([Fe^(2+)][H_2])/([Fe][H^+]^2)`D. `E_"cell"=E_"cell"^@-"0.0591"/2 "log" ([Fe][H_2])/([Fe^(2+)][H^+]^2)` |
Answer» Correct Answer - C `{:("At anode:",Fe to Fe^(2+) (0.001 M)+2e^-),("At cathode:",2H^(+)(1M)+2e^(-) to H_2"(1 atm)"),("Net reaction:",Fe+2H^(+) to Fe^(2+)+ H_2):}` Nernst equation for the given cell , `E_"cell"=E_"cell"^@-0.0591/2 "log"([Fe^(2+)][H_2])/([Fe][H^+]^2)` |
