If `E_(Fe^(2+)//Fe)^(@)=-0.440 V` and `E_(Fe^(3+)//Fe^(2+))^(@)=0.770 V`, then `E_(Fe^(3+)//Fe)^(@)` is -

Given E_(Fe^(3+)//Fe)^(@)=-0.036V and E_(fe^(2+)//Fe)^(@)=-0.44V . What is the value of E_(Fe^(3+)//Fe^(2+))^(@)

Given that E_(Fe^(2+)//Fe)^(.)=-0.44V,E_(Fe^(3+)//Fe^(2+))^(@)=0.77V if Fe^(2+),Fe^(3+) and Fe solid are kept together then

Given that E_(Fe^(2+)//Fe)^(.)=-0.44V,E_(Fe^(3+)//Fe^(2+))^(@)=0.77V if Fe^(2+),Fe^(3+) and Fe solid are kept together then
