Solution please the answer to this quest is given(-0.036V) Solution please the answer to this quest is given(-0.036V) ' If V. = 077 V. Calculate Share with your friends Share 0 Vartika Jain answered this Dear Student, Fe2+ + 2e- → Fe E°Fe2+/Fe=-0.44 V ...(i)So, ∆G°(i) = -nFE° =-2×96500×(-0.44) =84920 JFe3+ + e- → Fe2+ E°Fe3+/Fe2+=0.77 V (ii)So, ∆G°(ii) = -nFE° =-1×96500×(0.77) =-74305 JThe required equation isFe3+ + 3e- → FeThis can be obtained by adding (i) and (ii)So, ∆G°(iii) =∆G°(i)+∆G°(ii) =84920 J-74305 J =10615 J Also, ∆G°(iii) = -nFE°or, E°=-∆G°(iii)nF =-10615 J3×96500 =-0.036 VSo, E°Fe3+/Fe=-0.036 V 1 View Full Answer
