Cr(s) ---------------> Cr^3+ (aq) + 3e^- E0 = 0.74v
F2(g) + 2e^- -------------> 2F^- (aq) E0 = 2.87v
2Cr(s) ---------------> 2Cr^3+ (aq) + 6e^- E0 = 0.74v
3F2(g) + 6e^- -------------> 6F^- (aq) E0 = 2.87v
----------------------------------------------------------------------------------
2Cr(s) + 3F2(g) --------------------> 2Cr^3+ (aq) + 6F^- (aq) E0cell = 3.61v overall net reaction
2Cr(s) + 3F2(g) --------------------> 2Cr^3+ (aq) + 6F^- (aq) overall net ionic reaction
