Question 1

What is the Ecell for the following concentration cell at 25 °C:  

Pt(s) H2(g, 0.025 atm) H+ (0.012 M) H+ (aq, 1 M) H2(g, 1 atm) Pt(s)
2 H+(aq) + 2 e-→ H2(g) = 0. V

◦ -0.16 V
◦ +0.066 V
◦ -0.132 V
◦ 0.16 V
◦ -0.066 V

Question 2

What is the reduction half-reaction for the following overall galvanic cell reaction?

Co2+(aq) + 2Ag(s) → Co(s) + 2 Ag+(aq)

◦ Ag(s) + e-→ Ag+(aq)
◦ Ag+(aq) + e-→ Ag(s)
◦ Co2+(aq) + 2 e-→ Co(s)
◦ Co2+(aq) + e-→ Co(s)
