Answer 1

If the standard electrode potential of an electrode is greater than zero then we can infer that it's reduction is favourable.

Standard Electrode Potential

• There are two type of potentials possible I.e. oxidation potential and reduction potential.

• Oxidation potential :- The potential required for oxidation . For example:- $A=A^n +ne$

• Reduction potential :- The potential required for reduction of an ion. For example :-  $A^n+ne=A$

• IUPAC considers reduction potential as standard electrode potential of a substance.

• ∆G = -nF∆E

• Therefore, ∆G and ∆E will have opposite sign.

• The reaction is feasible when ∆G < 0 ,it implies it will be feasible when ∆E > 0.

• ∆G° and ∆E° are measurements taken at standard conditions.And hence, ∆G° = -nF∆E°
