The standard electrode potential $\mathrm{E}_{0}$ at a fixed temperature and in a given medium is dependent on
(a)only the electrode composition
(b)the electrode composition and the extent of the reaction
(c)the extent of the electrode reaction only
(d)the electrode reaction and the electrode composition
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
E° is a property of the electrode reaction (the couple and its stoichiometry) and of the electrode composition; it does not depend on how far the reaction has gone.
