Nernst equation describes the variation ...

Nernst equation describes the variation of electrode potential with concentration and temperature. Write cell reaction, overall reaction and calculate e.m.f at `25C^0` for the cell. Also write Nernst equation for the cell potential. `Mg//Mg_(10^(-3)M)^(2+)// Ag_(0.1M)^(+) // Ag` Given `E_(Mg^(2+)//Mg)^0 = 2.37V ` `E _(Ag^+//Mg)^0=0.8V`.
