Question 1

Calculate the cell potential for the following unbalanced reaction that takes place in an electrochemical cell at 25 °C when [Cr3+] = 0.945 M and [Zn2+] = 1.37 M

Zn(s) + Cr3+(aq) → Zn2+(aq) + Cr(s)

E°(Zn2+/Zn) = -0.76 V and E°(Cr3+/Cr) = -0.73 V

◦ -0.03 V
◦ -1.18 V
◦ +0.03 V
◦ +0.49 V
◦ +1.18 V

Question 2

Calculate the cell potential for the following unbalanced reaction that takes place in an electrochemical cell at 25 °C when [Cr3+] = 2.00 M and [Zn2+] = 0.00300 M

Zn(s) + Cr3+(aq) → Zn2+(aq) + Cr(s)

E°(Zn2+/Zn) = -0.76 V and E°(Cr3+/Cr) = -0.73 V

◦ +0.11 V
◦ +0.02 V
◦ +0.06 V
◦ -0.19 V
◦ +1.30 V
