1.

Consider the following standard reduction potentials,
Pb 2 +(aq) + 2 e- → Pb(s) E° = -0.13 V
I2(s) + 2 e- → 2 I-(aq) E° = +0.54 V
Under standard conditions,

Consider the following standard reduction potentials,
Pb 2 +(aq) + 2 e- → Pb(s) E° = -0.13 V
I2(s) + 2 e- → 2 I-(aq) E° = +0.54 V
Under standard conditions,

I2(s) is a stronger oxidizing agent than Pb 2+(aq) and Pb(s) is a stronger reducing agent than I-(aq).
Pb 2 +(aq) is a stronger oxidizing agent than I2(s) and I-(aq) is a stronger reducing agent than Pb(s).
I-(aq) is a stronger oxidizing agent than Pb(s) and I2(s) is a stronger reducing agent than Pb 2+(aq).
Pb(s) is a stronger oxidizing agent than I-(aq) and Pb 2+(aq) is a stronger reducing agent than I2(s).
