How to predict the feasibility of a cell reaction ? |
|
Answer» Solution :The feasibility of a REDOX reaction can be predicted with the HELP of the electrochemical series. (i) The net emf of the cell reaction `E_("cell")` can be calculated from the expression, `E^(@)""_(cell)=E^(@)""_(cathode)-E^(@)""_(anode)` (II) In GENERAL, if `E^(@)""_(cell)=`+ve, the reaction is feasible. `E^(@)""_(cell)=` -ve, the reaction is not feasible. |
