Which is the correct Nernst equation for reaction taking place in the following cell
Mg(s) | Mg2+ (aq) || Ag+ (aq) | Ag (1 atm)/Pt
1
Ecell = Eocell - × log\(\frac{[Ag+]^2}{[Mg^{2+}]}\)
2
Ecell = Eocell -\(\)\(\frac{0.0592}{n}\) × log \(\frac{[M^{2+}]}{[Ag^+]}\)
3
Ecell = Eo cell - \(\frac{0.0592}{n}\) × log[Mg2+] [Ag]2
4
Ecell = Eocell - \(\frac{0.0592}{n}\) × log \(\frac{[Mg^{2+}]}{[Ag+]^2}\)
