Question 1

Which of the following statements is true about a voltaic cell for which E°cell = –1.00 V?

◦ It has ΔG° < 0.
◦ The system is at equilibrium.
◦ It has K = 1.
◦ The cathode is at a higher energy than the anode.
◦ The reaction is nonspontaneous.

Question 2

Which of the following statements is true concerning the electrochemical cell depicted below?
Mg | Mg2+(aq) || Ni2+(aq) | Ni
Mg2+(aq) + 2e–→ Mg(s); E° = –2.38 V
Ni2+(aq) + 2e–→ Ni(s); E° = –0.23 V

◦ The cell reaction is spontaneous with a standard cell potential of 2.15 V.
◦ The cell reaction is spontaneous with a standard cell potential of 2.61 V.
◦ The cell reaction is nonspontaneous with a standard cell potential of –2.15 V.
◦ The cell reaction is nonspontaneous with a standard cell potential of –2.61 V.
◦ The cell is at equilibrium.
