The standard reduction potentials in V for Ag+ to Ag and Fe3+ to Fe2+ are +0.80

Question

The standard reduction potentials in V for Ag+ to Ag and Fe3+ to Fe2+ are +0.80 and +0.77, respectively. Calculate Delta G Degree (in kJ) for the following reaction. (F = 96,500 J/V'mol) Ag+(aq) + Fe2+(aq) Ag(s) + Fe3+(aq) 2.89 151.7 -151.7 -2.89 -80.1 Given the following information which of the following reactions will occur spontaneously as written? The standard reduction potentials in V for Zn2+ and Cu2+ are -0.76 and +0.34, respectively. What is the potential of the cell (in V) represented below? Zn | Zn2+(1.00 M) || Cu2+(0.100 M) | Cu -1.14 -0.42 +1.07 +1.10 +0.42
