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)
◦ F
2(
g)
◦ Mg
2+(

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.
Cd
2+(
aq) + 2 Fe
2+(
aq) → 2 Fe
3+(
aq) + Cd(
s)
◦
E° = -1.17 V, spontaneous
◦
E° = +1.17, nonspontaneous
◦
E° = + 1.17, spontaneous
◦
E° = -1.17 V, nonspontaneous
