Question 1

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, 0.0.0400 M) ∣∣ Ag+(aq, 1.25 M) ∣ Ag(s)


◦ 2.56 × 10-2
◦ 39.0
◦ 31.2
◦ 3.20 × 10-2

Question 2

Consider a cell based on the following reaction:

GeO(s) + H2O(l) + 2 Ag+(aq) → GeO2(s) + 2 H+(aq) + 2 Ag(s)


If [Ag+] = 1 M, at 25°C,
◦ pH = (E° - E)x0.0592 V.
◦ pH = 1/2(E - E°)x0.0592 V.
◦ pH = 1/2(E° - E)x0.0592 V.
◦ pH = (E - E°)/0.0592 V.
