Problem

The table below lists standard potentials for two different redox reactions that proceed spontaneously under standard conditions at 298 K.
ReactionOverall Chemical Equation (already balanced)E° (V)
A2 Ag⁺(aq) + Cu(s) → 2 Ag(s) + Cu²⁺(aq)+0.46
BFe²⁺(aq) + Ag⁺(aq) → Fe³⁺(aq) + Ag(s)+0.03
(a) Determine the equilibrium constant for Reaction A at 298 K. Show all calculation steps. (b) Determine the equilibrium constant for Reaction B at 298 K. Show all calculation steps. (c) Rank Reactions A and B in order of their driving force toward product formation under standard conditions. Justify the ranking quantitatively by referring to the values obtained in parts (a) and (b).
