Write the Nernst equation and EMF of the following cells at 298 K:
(i) Mg(s) | Mg2+(0.001 M) || Cu2+(0.001 M) | Cu(s)
(ii) Fe(s) | Fe2+(0.001 M) || H+(1 M) | H2(g) (1 bar) | Pt(s)

a) Need more information to determine.
b) EMF = E°cell - (0.0592/n)logQ
c) EMF = E°cell + (0.0592/n)logQ
d) EMF = E°cell + (0.0592/n)logQ
