Electrode potential values depends on

The correct option is D All of these
Electrode potential values depends on ionization energy, sublimation energy as well as hydration energy because all three factors affect the elements ability of accept or donate electrons.
Ionization energy: The energy required to remove the electron from the outermost valence shell.
Sublimation energy: The heat energy required to change one mole of a substance from solid state to gaseous state at STP (Standard Temperature and Pressure) conditions, in general.
Hydration energy: Amount of energy released when one mole of ions undergo hydration.
