Question 1

A voltaic cell is constructed with two Zn2+-Zn electrodes, where the half-reaction is

Zn2+ + 2 e- → Zn (s)E° = -0.763 V

The concentrations of zinc ion in the two compartments are 1.17 × 10-2 mol L-1 and 8.70 × 10-2 mol L-1, respectively. The cell emf is ________ V.
◦ 515
◦ -0.678
◦ -0.0850
◦ 0.170
◦ 0.0850

Question 2

The standard emf for the cell using the overall cell reaction below is +2.20 V:

2Al(s) + 3I2(s) → 2Al3+(aq) + 6I-(aq)

The emf generated by the cell when [Al3+] = 4.5 × 10-3 mol L-1 and [I-] = 0.15 mol L-1 is
◦ 2.55
◦ 2.36
◦ 2.08
◦ 2.44
◦ 2.32
