Calculate the maximum amount of work for the redox reaction between Cd(s) and Au^3+(aq) at 25 ̊C

Answer = 1.10 x 10^6 J

Can anyone please work this out?

Solutions

Expert Solution

Cd(s)    -------------> Cd2+ (aq) +   2e-   Eo = –0.403 V

Au3+ (aq) + 3e-     ----------> Au (s)      Eo = +1.498 V

__________________________________________

3 Cd (s) + 2 Au3+ (aq) -------> 3 Cd2+(aq) + 2 Au (s)

Eocell = Eored - Eooxidation

          = 1.498 - (-0.403)

Eocell = 1.901 V

delta Go = - n F Eocell

               = - 6 x 96485 x 1.901

delta Go = - 1.10 x 10^6 J

maxiumum work = 1.10 x 10^6 J
