Question 1

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 2 5°C. (The equation is balanced.)

Pb(s) + Br2(l) → Pb2+(aq) + 2 Br⁻(aq)

Pb2+(aq) + 2 e⁻ → Pb(s)

E° = -0.13 V

Br2(l) + 2 e⁻ → 2 Br⁻(aq)

E° = +1.07 V

◦ -0.60 V
◦ -1.20 V
◦ -0.94 V
◦ +0.94 V
◦ +1.20 V

Question 2

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 °C. (The equation is balanced.)

Sn(s) + 2Ag⁺(aq) → Sn2+(aq) + 2Ag(s)

Sn2+(aq) + 2 e⁻ → Sn(s)

E° = -0.14 V

Ag⁺(aq) + e⁻ → Ag(s)

E° = +0.80 V

◦ +1.08 V
◦ -1.08 V
◦ +0.94 V
◦ +1.74 V
◦ -1.74 V
