Question

Calculate the standard electrode potential for the following redox reaction at 298 K: Fe3+(aq) + e- → Fe2+(aq) Given that the standard electrode potential for the half-reaction Fe3+(aq) +  e- → Fe2+(aq) is +0.77 V.

Answer 1

The redox reaction given is already a half-reaction:Fe3+ aq  + e-  Fe2+ aq The standard electrode potential for this half-reaction is provided as +0.77 V. Since there is no other half-reaction to combine it with, the standard electrode potential for this redox reaction is simply the value given:E = +0.77 V
