Question

How many minutes will it take to plate out 325 g of sodium metal from molten Na3N using a current of 35.2 amps in an electrolyte cell?

Make sure to write half reactions at the anode, cathode and a net redox reaction that takes place in the cell.

1. A galvanic sell is constructed from silver in Ag+ (aq) and iron in Fe2+(aq) solutions and operates at 25⁰C:

a) Write the reduction/oxidation half-reactions in each compartment and the net reaction in the cell.

b) Write a cell notation/a diagram for this voltaic cell, identifying the anode and cathode (circle the anode and square the cathode).

c) Calculate the EMF of this cell when [Fe2+].10 M and [Ag+].50 M.

d) Is the net redox reaction spontaneous under conditions given in part (c)?__________ Why_________________

e) Calculate standard free energy change for the net redox reaction at 25^oC.

f) Calculate DG for the net redox reaction at 25^oC.
