Question 1

What is the relationship between the standard cell potentials, E°, for the following two galvanic cell reactions?

I.2 Ag+(aq) + Sn2+(aq) → Sn4+(aq) + 2 Ag(s)
II.2 Ag(s) +   Sn4+(aq) →   Sn2+(aq) + 2 Ag+(aq)

E°(I) = E°(II)
E°(I) = -   E°(II)
E°(I) = - E°(II)
E°(I) =   E°(II)

Question 2

What is the standard cell potential for the reaction below?

Pb(s) + Br2(l) → Pb2+(aq) + 2 Br-(aq)


The standard reduction potential is -0.13 V for the Pb2+/Pb half-cell and +1.09 V for the Br2/Br- half-cell.
◦ -0.95 V
◦ -1.22 V
◦ +0.95 V
◦ +1.22 V
