Refer to the following half-reactions and their E° values:
Bi+(aq) + e– → Bi(s) E° = 0.240 V
W3+(aq) + 3 e– → W(s) E° = 0.100 V
Ga3+(aq) + 3 e– → Ga(s) E° = –0.549 V
For the combination of reactions that produces the largest voltage at 25°C, provide the overall cell reaction and determine the cell potential (E°), ΔG° (in kJ), and equilibrium constant (K).
