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
e–	0

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
