Question 1

At 25°C, E° = +1.88 V for a cell based on the reaction

3 AgCl(s) + Al(s) → 3 Ag(s) + Al3+(aq) + 3 Cl-(aq).


Find the cell potential E if [Al3+] = 0.20 M and [Cl-] = 0.010 M.
◦ +2.04 V
◦ +2.28 V
◦ +2.01 V
◦ cannot be calculated without the amounts of AgCl, Al, and Ag

Question 2

Given that E° = +0.897 V, calculate E at 25°C for

Pb(s) ∣ Pb2+(0.0400 M) ∣∣ Fe3+(0.200 M), Fe2+(0.0100 M) ∣ Pt(s)


◦ +1.015 V
◦ +0.779 V
◦ +0.935 V
◦ +1.134 V
