![5. Followed from the previous question, it was determined that K for the reaction at
25°C between CIO and H2O2 was 1.2 x 10. Calculate AG° and E celi from the
given K. What is the implication of K having such an enormous value? Use Faraday
constant, F=96485 C/mol.
6. Calculate the Ecel value (non-standard state) at 298 K for the cell based on the reaction,
Fe"(ag) + Cu'(ag)– Fe"(aq) + Cu (ag),
when [Fe"]=[Cu'] - 2.56 x 10-3 M and [Fe2*]= [Cu*]-8.25 x 10 M.
Fe"(aq) + e - Fe2"(aq) E = 0.770 V
Cu"(aq) + e - Cu (ag) E = 0.153 V
