Question 1

The equilibrium constant at 25°C for the reaction Al + 3Cu2+ 2Al3+ + 3Cu is approximately

◦ 10203

​


◦ 1034

​


◦ 1068

​


◦ 10–203

​


◦ None of these are correct.

Question 2

The following has a potential of 0.34 V:

Cu2+(aq) + H2(g) → 2H+(aq) + Cu(s)

If the concentrations of the ions were 1.0 M and the pressure of H2 were 1.0 atm, then E° for the half-reaction Cu2+(aq) + 2e–→ Cu(s) would be


◦ –0.34 V
◦ –0.17 V
◦ 0.17 V
◦ 0.34 V
◦ None of these are correct.
