Calculate cell potential for the following reaction?

Calculate the cell potential for the following reaction as written at 79 °C, given that [Cr2 ] = 0.882 M and [Fe2 ] = 0.0170 M. Standard reduction potentials can be found here. Cr(s)+Fe2+(aq) --> (equilibrium arrow) Cr2+(aq)+Fe(s) would I use RF/nT formula? what would n be?
