The formula for the calculating standard electrode potential (E° is given below 'anode If AGo is positive then and E° is negative If the Eo is negative, the reaction is non-spontaneous, If the Eo is positive, the reaction is spontaneous
Eo of the given reaction is negative, therefore the reaction is non-spontaneous.
