Question 1

The reduction potentials for Ni2+ and Sn2+ are as follows:
Ni2+ + 2e Ni, E° = –0.231 V
Sn2+ + 2e Sn, E° = –0.140 V

Calculate the equilibrium constant at 25 °C for the reaction:
Sn2+ + Ni Sn + Ni2+

3.6 × 1012

35
5.9
8.3 × 10–4

1.2 × 103


Question 2

The standard free energies of formation of several species are:
 
kJ/mol
H+(aq)
0
H2O(l)
–237.0
CH3OH(aq)
–163.0
HCOOH(aq)
–351.2

What is the standard reduction potential of methanoic acid in aqueous solution (i.e., for HCOOH + 4H+ + 4e CH3OH + H2O)?


0.126 V
0.506 V
–0.718 V
–0.126 V
1.946 V
