a) Calculate the cell potential at 25°C for the cell

Fe(s) I (Fe2+ (0.100 M) II Pd2+ (1.0 × 10-5 M) I Pd(s)

given that the standard reduction potential for Fe2+/Fe is -0.45 V and for Pd2+/Pd is +0.95 V. - Please show the steps

b) Based on the half-reactions and their respective standard reduction potentials below, the strongest reducing agent is ________, and the strongest oxidizing agent is ________.

      Ag+ (aq) + e- → Ag(s)            0.80 V

            2 H+ (aq) + 2 e- → H2 (g)       0.00 V

            Cd2+ (aq) + 2 e- → Cd(s)        -0.40 V

The answer is

Cd, Ag+

Can you please explain to me why this is the right answer.
