Question

For the reaction that occurs in the voltaic cell Fe(s)|Fe^2+(aq)||Cr^3+(aq),Cr^2+(aq)|Pt(s)

a) Determine delta G not
b)Determine K

Answer 1

Calculate E for the left half of the cell using the Nernst equation. Do the same for the right half of the cell. Determine the cell potential, then
delta Go = -nFE
Then delta Go = -RT*ln K
