Question 1

For a galvanic cell that uses the following two half-reactions,

Cr2O72-(aq) + 14 H+(aq) + 6 e-→ 2 Cr3+(aq) + 7 H2O(l)
Pb(s) → Pb2+(aq) + 2 e-

how many moles of Pb(s) are oxidized by three moles of Cr2O72-(aq)?
◦ 3
◦ 6
◦ 9
◦ 18

Question 2

For the cell reaction at 25 °C Cu2+(aq) + Zn(s) → Cu(s) + Zn2+(aq), E°cell = +1.100 V. What is the equilibrium constant for this reaction?
◦ 3 × 10-19
◦ 2 × 1037
◦ 2 × 10-37
◦ 3 × 1018
◦ 3 × 10-18
