Spontaneous ...
Happens all by itself; typically unpredictable
Non-spontaneous...
You have to do something to make it happen.
In the context of "spontaneous vs non-spontaneous," a reaction is considered spontaneous if it occurs on its own without needing external influence. On the other hand, a non-spontaneous reaction requires external energy input to occur.
The standard cell potential for the non-spontaneous reaction between silver and copper ions (Ag+ and Cu2+) is determined by subtracting the reduction potential of Ag+ from that of Cu2+. The cell potential would be negative as the reaction is non-spontaneous, indicating that an external voltage larger than the calculated value would be needed to drive the reaction in the reverse direction.
The significance of delta G in chemical reactions is that it indicates whether a reaction is spontaneous or non-spontaneous. A negative delta G value means the reaction is spontaneous and can proceed on its own, while a positive delta G value means the reaction is non-spontaneous and requires external energy input to occur.
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
An electrolytic cell uses an external power source to drive a non-spontaneous chemical reaction. Electricity is used to force electrons through the cell, causing a redox reaction to occur at the electrodes. This allows for the production of new chemical compounds or the separation of substances.

A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
Electrons flow in the opposite direction.
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.

In an electrolytic cell, electrical energy is used to drive a non-spontaneous reaction, causing a chemical change. In contrast, a galvanic cell generates electrical energy from a spontaneous chemical reaction. Electrolytic cells are often used in processes like electrolysis, while galvanic cells are used in batteries.
Forming a triacylglyceride from three fatty acids and glycerol is an anabolic reaction that is endergonic (requires energy input) and non-spontaneous under normal cellular conditions.
