Nernst Equation:

Ecell = E°cell – RT[Zn2+]/ nF[Cu2+]

Galvanic cell reaction:

Zn(s)|Zn2+(aq)||Cu2+(aq)|Cu(s)

Reaction in Anode:

oxidation half-cell

Zn(s) → Zn2+ (aq)+ 2e

Reaction in Cathode:

reduction half-cell

Cu2+ (aq)+ 2e-→ Cu(s)

Complete Reaction Involved:

Zn(s) + Cu2+ (aq) → Zn2+(aq) +Cu(s)

Nernst Equation of the cell reaction:

Ecell = E°cell – 0.059/2[Zn2+]/[Cu2+]
