Spontaneous ...Happens all by itself; typically unpredictableNon-spontaneous...You have to do something to make it happen.

Spontaneous
if the external circuit is replaced by a source of electricity that opposes the voltaic cell, the electrode reactions can be reversed.Now,the external source pushes the electrons in the opposite direction and supplies energy or work to the cell so that the reverse non-spontaneous reaction occurs.

Anabolic, endergonic, non-spontaneous
Electrons flow in the opposite direction.

Galvanic cells run spontaneously and do not require any energy to run to completion, but Electrolytic cells require energy to run to completion, and are non-spontaneous.
