Write the Nernst equation and emf of the following cells at 298 K: (i) Mg(s) | Mg* (0.001M) || Cu**(0.0001 M) | Cu(s) (ii) Fe(s) | Fe²(0.001M) || H*(1M)|H₂(g)(1bar) | Pt(s) (iii) Sn(s) | Sn*(0.050 M) || H*(0.020 M) | H.(g) (1 bar) | Pt(s) (iv) Pt(s) | Br.) | Br(0.010 M) || H*(0.030 M) | H₂(g) (1 bar) | Pt(s). Write the Nernst equation and emf of the following cells at 298 K: (i) Mg(s) | Mg* (0.001M) || Cu**(0.0001 M) | Cu(s) (ii) Fe(s) | Fe²(0.001M) || H*(1M)|H₂(g)(1bar) | Pt(s) (iii) Sn(s) | Sn*(0.050 M) || H*(0.020 M) | H.(g) (1 bar) | Pt(s) (iv) Pt(s) | Br.) | Br(0.010 M) || H*(0.030 M) | H₂(g) (1 bar) | Pt(s).
