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
