Determine the standard electrode potential, given that the standard reduction potential for the half-reaction, Ag+ (aq) + e- → Ag(s) is +0.80 V and the standard oxidation potential for the half-reaction, Fe(s) → Fe2+(aq) + 2e-, is -0.44 V. Using this information, predict whether or not the reaction Ag(s) + Fe2+(aq) → Fe(s) + Ag+(aq) will occur spontaneously under standard conditions.
