Calculate E°_cell for the cell for the reaction 2 Ga(s) + 3 Sn⁴⁺(aq) → 3 Sn²⁺(aq) +2 Ga³⁺(aq) . The standard reduction potentials are as follows:
Ga³⁺(aq) + 3 e− → Ga(s)
E° = -0.55 V
Sn⁴⁺(aq) + 2 e− → Sn²⁺(aq)
E° = 0.15V

Quizplus · Accepted Answer

The standard cell potential (E°cell) is calculated by subtracting the standard reduction potential of the anode (the more negative value) from the standard reduction potential of the cathode (the more positive value). Here, Ga is oxidized (anode reaction) and Sn2+ is reduced (cathode reaction). Thus, E°cell = 0.15 V (for Sn2+/Sn) - (-0.55 V) (for Ga3+/Ga) = 0.70 V.
