Calculation of Standard Cell Potential in Electrochemical Cell

Very Hard General Chemistry Electrochemistry

In an electrochemical cell, the overall cell reaction can be represented by the following half-reactions:

Anode: Zn(s) → Zn²⁺(aq) + 2e^-

Cathode: Cu²⁺(aq) + 2e^- → Cu(s)

Calculate the standard cell potential (E^°) for the cell under standard conditions. Given the standard electrode potentials: E^°(Zn²⁺/Zn) = -0.76 V and E^°(Cu²⁺/Cu) = +0.34 V. Which statement below about the electrochemical cell is correct?

The cell potential is negative, indicating a spontaneous reaction.

The cell potential can be calculated as +1.10 V.

This reaction represents a reduction at the anode.

The reaction will favor the formation of Zn<sup>2+</sup> ions.
