1. Determine the standard free-energy change ΔG o for the following reaction at the 25oC from standard electrode potentials. Suppose you will need to use the relevant half-reactions to balance it.
Fe 3+ (aq) + Hg (l) → Fe 2+ (aq) +Hg 22+ (aq)
2. Determine the standard cell potential for Sn2+ (aq) + Ni(s)→ Sn(s) + Ni2+ is 0.10 M. What is the potential of this cell?
