Given, standard electrode potentials, Fe2+ + 2e- →Fe, E° = -0...
Fe2+ +2e→Fe, Eo = −0.440 ......(1)
Fe3+ + 3e− → Fe, Eo = −0.036.......(2)
The standard electrode potential for Fe3+ +e →Fe2+ is obtained by substracting the value of the standard electrode potential for first reaction from the standard electrode potential for second reaction. 
−0.036 −(−0.440) = 0.404V
