"WebA voltaic cell converts the DG of a spontaneous redox reaction into the kinetic energy of electrons. The cell potential (Ecell) of a voltaic cell depends on the difference in electrical potential between the two electrodes. Cell potential is also called the voltage of the cell or the electromotive forces (emf). Ecell > 0 for a spontaneous process. " - In a voltaic cell electrons move:
