How to predict the feasibility of a cell reaction ?

Text Solution

Verified by Experts

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.
