Question 1

What is the potential at 25°C for the following cell?
Cr | Cr3+(0.010 M) || Ag+(0.00030 M) | Ag
Cr3+ + 3e Cr     E° = –0.73 V
Ag+ + e Ag       E° = 0.80 V

2.09 V
1.36 V
0.95 V
1.70 V
1.50 V

Question 2

What is the value of the reaction quotient, Q, for the voltaic cell constructed from the following two half-reactions when the Zn2+ concentration is 0.0120 M and the Ag+ concentration is 1.25 M?
Zn2+(aq) + 2e→ Zn(s); E° = –0.76 V
Ag+(aq) + e→ Ag(s); E° = 0.80 V
