    If activity coefficient is less than 1.0, it indicates that molecules have strong attractive force and therefore more energy is required to separate them.
    Conversely, when activity coefficient is greater than 1.0, it implies that molecules have strong repelling force In this case, lesser energy is needed to separate the constituent molecules.

    12:37 An electrode does not "give" current to electrons; rather, it serves as a conductor that allows electrons to flow in a circuit. In an electrochemical cell, for example, oxidation and reduction reactions occur at the electrodes, facilitating the movement of electrons. The flow of electrons constitutes the electric current.
