Ecell 0.0592 loge n CP= [-Anode] where [Cathale in All the reaction below Q = 1 so log a=0 80 E coll max <D zolant +0.596 80 3+ Co.lom) Cu ²+ Co.1) 1 cu 40.34 Ecell = 0.34 + (10.76 1.1 - Ecell = 1.1 ce 4 (0.10 ) | cu Fel Fe2+ (0-10 M) 0.41v 0.34 Ecell = (0.414 0.34) V Ecoll= 0.75V <83 mg / Mght (ONOM) || cupe (0-10M)/ cu L 0.34V 2.38 Ecoll = 2.38 +0.347 Ecoll= 2.72 V (4.) mg/mg²t 27 In an - 0.76 2.38 Ecoll 2.38 -0.76 Ecoll = 1.62 V

I have calculated the Ecell for all the datas.

And after that i calculated the cell potential.
