Question 1
Consider the galvanic cell,

Which one of the following changes to the cell would cause the cell potential to increase (i.e., become more positive)?
◦ increase the mass of Fe(
s)
◦ decrease the mass of Fe(
s)
◦ increase the [Fe
2+] concentration
◦ increase the [Pb
2+] concentration
Question 2
Calculate the value of the reaction quotient,
Q, for the galvanic cell expressed using shorthand notation below. Use the balanced chemical equation that has the smallest whole number stoichiometric coefficients.
Zn(s) ∣ Zn2+(aq, 0.0100 M) ∣∣ Ag+(aq, 1.10 M) ∣ Ag(s)
◦ 121
◦ 110
◦ 8.26 × 10
-3◦ 9.09 × 10
