Homework Answers
K2CrO4 + 2Ag + 2FeCl3 à Ag2CrO4 + 2FeCl2 +2KCl
2Ag + CrO42- → Ag2CrO4 + 2e-
2FeCl3 + 2e- → 2FeCl2 + 2Cl-
delta G = -nFEcell
-62.5 x 103 J/mol= -(2 mol) (96500 c/mol) Ecell
Ecell = 62.5/(2 x 96.5) = 0.324 V
Ecell = Ecello – RT/nF lnq
0.324 = RT/nF ln [Red/Oxid]
0.324 = SPEFe -SPEAg
Fe+3/Fe2+ = 0.77
SPEAg = 0.77-0.324 = 0.45V
