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