Given the following reduction potentials:                                                               Eored Cr3+(aq)  + 3e- →  Cr(s)                      –0.74 V Fe3+(aq)  +  e- →  Fe2+(aq)                 +0.77 V Calculate the equilibrium constant, K, for the following reaction.               Cr(s)    + 3    Fe3+(aq)   →   Cr3+(aq) + 3 Fe2+(aq) Hint:  Remember that a voltaic cell runs on a spontaneous redox reaction.   Hint: Make sure to determine the total moles of electrons transferred for the cell.
