Question 1

Based on the following information,

F2(g) + 2 e-→ 2 F-(aq) = +2.87 V
Li+(aq) +   e-→   Li(s) = -3.04 V

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

Question 2

Calculate Ecell at 25 °C for the following voltaic cell. Ksp for NiCO3(s) is 1.42 × 10-7.

Ni(s) Ni2+(aq) [sat'd NiCO3(s)] Ni2+(aq) (0.010M) Ni(s)

The half-reaction is:  Ni2+(aq) + 2 e-→ Ni(s)   = -0.257 V
◦ +0.257 V
◦ -0.257 V
◦ 0.000 V
◦ +0.0844 V
◦ +0.0422 V
