The half cell reaction with lesser `E^(@)` value takes place at the anode while the other takes place at the cathode. Thus
`{:("At anode: " 2I^(-) to I_(2)+2e^(-) " (oxidation)"),("At cathode : " Br_(2)+2e^(-) to 2Br^(-) " (reduction )"),("cell reaction: " bar(" "2I^(-) +Br_(2)to I_(2) +2Br^(-))):}`
