The standard electrode potential are for the following reactions : Fe_((s)) rarr Fe_((aq.))^(2+) + 2e , E^(@) = 0.48 V Cr^(3+) + e rarr Cr_((aq.))^(2+) , E^(@) = -0.41 V If excess of Fe_(s) is added to a solution in which [Cr^(3+)] = 1M, what will be maximum value of [Fe^(2+)] when equilibrium is attained at 298 K ? |
