Question

a) Write out the overall cell reaction occurring in the following voltaic cells. Draw a diagram (with two beakers) showing appropriate metals and solution contents. Write the appropriate half reactions. Label the anode and the cathode and show the direction of electron flow.

Cd(s) | Cd²⁺(aq) || Ag⁺(aq) | Ag(s)

 

 

 

 

 

An electrochemical cell is composed of a silver electrode in a 0.025 M Ag⁺ solution and a cadmium electrode into a 0.15 M Cd²⁺ solution.

a)        Write out the spontaneous cell reaction that will occur.

                       

b)       Determine E_cell° and E_cell at 298 K for this electrochemical cell.

 

c)       What is the equilibrium constant for this reaction at 298 K?
