use the appropriate standard reduction potentials in the appendix of your book to determine the equilibrium constant at 285 K for the following reaction under acidic conditions
4H+(aq) + MnO2(s)+2Fe+2(aq)----> Mn+2 (aq)+2Fe3+(aq)+2H2O(l)
The reductions potentials are 1.23 V and 0.770 V for the reduction and oxidation equations. I still can't figure out the answer.
