To determine the standard electrode potential (E°) of the given electrochemical cell, we will follow these steps: ### Step 1: Understand the relationship between efficiency, ΔG, and ΔH The efficiency of the cell is given as 84%. The relationship between efficiency, Gibbs free energy change (ΔG), and enthalpy change (ΔH) can be expressed as: \[ \text{Efficiency} = \left( \frac{-\Delta G}{\Delta H} \right) \times 100 \] ...
