Question

Consider the cell notation below:

Sn(s)|Sn2+||H+|H2|Pt(s)

 

2 H2O + 2e–  →  H2 + 2 OH–

–0.83 V

Sn2+ + 2e–  →  Sn

–0.14 V

2 H+ + 2e–  →  H2

0.00 V

Sn4+ + 2e–  →  Sn2+

+0.13 V

O2 + 4 H+ + 4e–  →  2 H2O

+1.23 V

 

R = 8.314 J/mol∙K

F = 96,485 J/mol∙V

A. What is the value of the standard cell potential, Eocell (in V)?

B. What is the ΔG° value (in J) for the reaction at 298 K?
