From the following E° values for the half-cells:(i) D → D2+ + 2e−; E° = −1.5 V (ii) B+ + e− → B; E°

Question

From the following E° values for the half-cells:

(i) D → D²⁺ + 2e⁻; E° = −1.5 V (ii) B⁺ + e⁻ → B; E° = − 0.5 V

(iii) A³⁻ → A²⁻ + e⁻; E° = 1.5 V (iv) C²⁺ + e⁻ → C⁺; E° = +0.5 V

Which combination of two half-cells would result in a cell with largest potential?

Accepted Answer

For (i) & (iii);$E_{cell}^{o} = 3.0	ext{ V}$
