Question 1

The standard emf for the cell using the overall cell reaction below is +0.48 V:

Zn(s) + Ni²⁺(aq) → Zn²⁺(aq) + Ni(s)

The emf generated by the cell when [Ni²⁺] = 6.50 mol L-1 and [Zn²⁺] = 0.500 mol L-1 is

◦ 0.55
◦ 0.50
◦ 0.51
◦ 0.45
◦ 0.61

Question 2

The gas OF2 can be produced from the electrolysis of an aqueous solution of KF, as shown in the equation below:

OF2(g) + 2H+(aq) + 4 e- → H2O(l) + 2F-(aq)

E° = +2.15 V

Using the given standard reduction potential, calculate the amount of OF2 that is produced, and the electrode at which the OF2 is produced, upon the passage of 0.480 faradays through an aqueous KF solution.
◦ 26.0 g of OF2 at the anode
◦ 6.48 g of OF2 at the cathode
◦ 6.48 g of OF2 at the anode
◦ 26.0 g of OF2 at the cathode
