Electrochemical Cell Potential for Daniell Cell

Very Hard General Chemistry Electrochemistry

In an electrochemical cell, zinc serves as the anode while copper serves as the cathode in a Daniell cell setup. The zinc electrode is dipped in a 1.0 M zinc sulfate solution, while the copper electrode is submerged in a 1.0 M copper(II) sulfate solution. Using standard reduction potentials, the overall reaction in the cell can be derived.

Given that the standard reduction potentials are, E°(Cu2+/Cu) = +0.34 V and E°(Zn2+/Zn) = -0.76 V, calculate the standard cell potential (E°cell) and identify which of the following statements about the cell reaction is true.
