A galvanic cell is constructed as follows. One half cell consists of a platinum wire immersed in a solution containing 1.0 M Sn2+ and 1.0 M Sn4+; the other half-cell has a thallium rod immersed in a solution of 1.0 M Tl1.
(a) Write the half-cell reactions and the overall reaction.
(b) What is the equilibrium constant at 25°C?
(c) What is the cell voltage if the T11 concentration is increased tenfold? (E°Tl1/Tl = 20.34 V.)
