Question 1

Based on the following information,

F2(g) + 2 e- → 2 F-(aq)E° = +2.87 V
Mg2+(aq) + 2 e- → 2 Mg(s)E° = -2.37 V

which of the following chemical species is the strongest reducing agent?
◦ Mg(s)
◦ F2(g)
◦ Mg2+(aq)
◦ F-(aq)

Question 2

Using the following standard reduction potentials,

Fe3+(aq) + e- → Fe2+(aq)E° = +0.77 V
Cd2+(aq) + 2 e- →Cd(s)E° = -0.40 V

calculate the standard cell potential for the cell reaction given below, and determine whether or not this reaction is spontaneous under standard conditions.

Cd2+(aq) + 2 Fe2+(aq) → 2 Fe3+(aq) + Cd(s)

◦ E° = -1.17 V, spontaneous
◦ E° = +1.17, nonspontaneous
◦ E° = + 1.17, spontaneous
◦ E° = -1.17 V, nonspontaneous
