Write the cell reaction that occurs when the following half-cells are combined. `I_(2)+2e^(-)to 2l^(-)(IM) , " "E^(@)=0.54 V` `Br_(2)+2e^(-)to 2Br^(-)(IM) , " "E^(@)=1.08 V` |

Answer» 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^(-))):}` |
