Homework Help: Electrochemistry - HW

  1. Mar 13, 2010 #1
    1. The problem statement, all variables and given/known data
    Sn + 2 Ag+ --> Sn2+ + 2 Ag

    a) Calculate the standard voltage of a cell involving the system above. (I got +0.94 Volts).

    b) What is the equilibrium constant for the system above? (I got 5.71 E 31)

    c) Calculate the voltage at 25 degrees celsius of a cell involving the system above when the concentration of Ag+ is 0.0010 molar and that of Sn+2 is 0.20 molar. (I got + 0.783 volts)

    2. Relevant equations

    Eocell = Ered - Eox

    Nernst Equation - Ecell = Eocell - 0.0592/n logQ

    3. The attempt at a solution

    Above.
