          Write the half-cell and overall-cell reactions for the following cells. Calculate the electromotive force (emf) values of the cells at room temperature.

Zn|ZnSO4(0.01 M)|| CuSO4(0.001 M)|Cu
Pb|Pb(NO3)2(0.01 M)||KCl(sat'd), Hg2Cl2(s)|Hg
Zn|ZnSO4(0.01 M)||FeSO4, Fe2(SO4)3, H2SO4|Pt, each species at 1 mM

The activity coefficients of Zn2+, Cu2+, Pb2+, Fe3+ and Fe2+ are 0.458, 0.757, 0.708, 0.256 and 0.546, respectively.

Step 1

**Cell 1: Zn|ZnSO4(0.01 M)|| CuSO4(0.001 M)|Cu** - Anode (oxidation): \( \text{Zn} \rightarrow \text{Zn}^{2+} + 2e^- \) - Cathode (reduction): \( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \) **Cell 2: Pb|Pb(NO3)2(0.01 M)||KCl(sat'd), Hg2Cl2(s)|Hg** - Anode Show more…
