Phases are optional. Do not include the concentrations. Incorrect. To determine the net ceil reaction, start by multiplying one or both of the half-reactions by a small integer (such as 2 or 3) to balance the electrons. Then, Calculate the following values at 25.0 using standard a en as as needed. sum the two half-reactions. Number Number E1.015 AG1959 kJ/mol Number Number AG. 2084 kJ/ mol

Explanation / Answer

Part A

   2Ag+(aq)+Sn(s) ---> 2Ag(s)+Sn2+(aq)

E0cell = E0cathode - E0anode

        = (0.8)-(-0.13)

        = 0.93 v

   DG0 = - nFE0cell

       = -2*96500*0.93

     = -179.490 kjoule

Ecell = E0cell - (0.0591/n)log((Sn2+)/(Ag+)^2)

        = 0.93-(0.0591/2)log(0.0155/3.5^2)

        = 1.01 v

   DG0 = - nFE0cell

       = -2*96500*1.01

       = -194.93 kj
