Question

How to determine feasibility of reaction from standard electrode potential value

Answer 1

Answer:

if you calculate the voltage of a cell and it happens to be less than 0.3v, a reaction does not happen.

Explanation:

feasibility cannot be predicted by one single electrode potential value. you need to find the voltage of the cell, i.e,

Electrode potential of electrode where reduction happens - electrode potential where oxidation happens.

if this value is less than o.3v, the reaction generally does not happen.

sometimes, there are exceptions, though. sometimes, it is said that even if electrode potential is greater than 0.3 v but the rate of reaction is very slow , the reaction does not happen.....

hope that helps XD
