  1. Consider the same diagram of a galvanic cell as in previous question,

             

         where the half-cells are Ag|AgNO3(aq) and Ni|Ni(NO3)2(aq), and the electrode potentials are as follows:

             Ag+(aq)   +  e–   -->  Ag(s);    Eo =   0.80 V

            Ni2+(aq)  +  2e–  -->  Ni(s);     Eo = – 0.23 V

         What is the Ecell at 25oC when the electrolyte concentrations are: [Ag+] = 1.3 x 10–5 M and [Ni2+] = 0.10 M.  

         (A) 1.15 V

         (B) 1.30 V

         (C) 0.76 V

         (D) 0.91 V
