A chemist wishes to determine the concentration of CrO42- electrochemically. A cell is constructed consisting of a saturated calomel electrode (SCE) and a silver wire coated with Ag2CrO4. The ° value for the following half reaction is +0.446 V relative to the standard hydrogen electrode.
Ag2CrO4 + 2 e- 2 Ag + CrO42-
(a) Calculate cell and ΔG at 25°C for the cell reaction when [CrO42-] = 1.00 mol/L.
E cell __________V
ΔG ___________kJ
