INSTANT ANSWER

Use the appropriate standard reduction potentials below to determine the equilibrium constant at 251 K for the following reaction under acidic conditions. $$4H+(aq)+MnO2?(s)+2Fe2+(aq) Mn2+(aq)+2Fe3+(aq)+2H2?O(l) Standard reduction potentials: $$MnO2?(s)+4H+(aq)+2e? Mn2+(aq)+2H2?O(l) $$E° = 1.23 V $$Fe3+(aq)+e? Fe2+(aq) $$E° = 0.770 V
