chlorine dioxide ( ClO2) which is produced by the reaction

 2 NaClO2 +  Cl2   ---->     2 ClO2     +   2 NaCl
has been tested as a disinfectant for municipal water treatment.

a. calculate E^0, delta G^0 and K at 25 degree celcius for the production of ClO2

im doing as

reduction  
Cl₂  + 2e ----> 2 Cl -    E = + 1.36
and
oxidation
2ClO₂^-   ---->   2ClO₂  + 2 e     What is E for this reaction ? ?  


then E for reaction can be calculated  and also G can be calculated
G = n F E
and for K         Log K = ( n / 0.059 ) E cell
