Calculate the Ecell value at 298 K for the cell based on the reaction: Cu(s) + 2Ag+ (aq) → Cu2+ (aq) + 2Ag(s) where [Ag+] = 0.00350 M and [Cu2+] = 7.00x10-4 M. The standard reduction potentials are shown below: Ag+(aq) +e → Ag(s) E° = 0.7996 V Cu2+ (aq) + 2e -→ Cu(s) E° = 0.3419 V 2nd attempt Ecell = V

K = 1.3 * 106 for the disproportionation reaction of Cu+ at 298 K. Calculate the E°cell for this rxn at 298K The latimer Diagram for Cu+ has: +0.159 V +0.520 V Cu2+ ---> Cu+ --> Cu(s) And then Cu2+ --> Cu (s) = 0.340 V So for Ecell would I just do Ecell = (0.520V - (-0.159V))? ... if not how come?

Chem 1212 Lab Report on electrochemistry
Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...
