1.	Using the standard electrode potential, find out the pair between which redox reactions is not possible ? E_(Fe^(+3)//Fe^(+2))^(Ө)=+0.77"volt",E_(I_(2)//I^(-))^(Ө)=+0.54"volt" E_(Cu^(+2)//Cu)^(Ө)=+0.34"volt",E_(Ag^(+)//Ag^(-))^(Ө)=+0.80"volt"
Answer» `Fe^(+3)andI^(-)` `Ag^(+)andCu` `Fe^(+3)andCu` `AgandFe^(+3)` SOLUTION :If value of `E_("cell")^(Ө)` BECOMES negative, that REACTION is not POSSIBLE.
