Question

Given the half-reactions: Zn²⁺ + 2e⁻ → Zn (E° = -0.76 V) and Cu²⁺ + 2e⁻ → Cu (E° = +0.34 V), calculate the standard cell potential for the galvanic cell and determine which reaction is more likely to occur.

Accepted Answer

E°_cell = +1.10 V; Cu²⁺ reduction is more likely.

Answer

E°_cell = +0.42 V; Zn²⁺ reduction is more likely.

Answer

E°_cell = +0.42 V; Cu²⁺ reduction is more likely.

Answer

E°_cell = -1.10 V; Zn²⁺ reduction is more likely.
