Problem

For the reaction

2\text{Fe}^{3+}(aq) + 2\text{I}^{-}(aq) \rightarrow 2\text{Fe}^{2+}(aq) + \text{I}_2(aq)

thermochemical data give

\Delta H^{\circ} = +12\,\text{kJ}

and the equilibrium constant

K = 4.6 \times 10^{8}

. The standard cell potential is measured as

+0.70\,\text{V}

. Based solely on the sign of the standard cell potential, predict whether the reaction is thermodynamically favorable under standard conditions and state your reasoning briefly.
