Homework Statement


An iron-nickel cell uses a salt bridge to join a half-cell containing a strip of iron in a 1mol/L solution of Fe2+ to a half cell which contains a strip of nickel in a 1mol/L Ni2+ solution. Calculate Ke for the reaction.


Homework Equations



∆E = ∆E⁰ - .0592V/n log Q

The Attempt at a Solution



so using ∆E⁰= ∆E⁰r (cathode) - ∆E⁰r (anode), I know that ∆E⁰= .66V, and I also know that at equilibrium ther is 0V, so ∆E =0. I know that Q is = to Ke, so i need to solve for Q. Problem is I don't know how to find the value of n (the amount, in moles, of electrons transferred according to the cell reaction)
