Standard Cell Potential Determination

Very Hard General Chemistry Electrochemistry

In an electrochemical cell, a redox reaction occurs between two half-cells, with one being an oxidation half-cell and the other being a reduction half-cell. Given a galvanic cell composed of a zinc electrode in a 1.0 M ZnSO4 solution and a copper electrode in a 1.0 M CuSO4 solution, calculate the standard cell potential (Ecell) at 25°C. The standard reduction potentials are: E°(Cu2+/Cu) = +0.34 V and E°(Zn2+/Zn) = -0.76 V. Which of the following statements is true about the calculated standard cell potential?
