Question
Deduce from the following E - values of half cells, what combination of two half cell would results in a cell with the largest potential -
I. A + eΘ → A- EΘ = - 0.24 V
II. BΘ + eΘ → B2- EΘ = + 1.25 V
III . CΘ + 2eΘ → C3- EΘ = - 1.25 V
IV. D + 2eΘ → D2- EΘ = + 0.68 V
I. A + eΘ → A- EΘ = - 0.24 V
II. BΘ + eΘ → B2- EΘ = + 1.25 V
III . CΘ + 2eΘ → C3- EΘ = - 1.25 V
IV. D + 2eΘ → D2- EΘ = + 0.68 V
Options
