The Gibbs free energy will always be negative for a spontaneous reaction at constant temperature and pressure. This suggests that the reaction is thermodynamically favorable and can proceed without the input of external energy.
In electrolysis, electrical energy is converted into chemical energy. This process involves using an electric current to drive a non-spontaneous chemical reaction, resulting in the separation of compounds into their constituent elements.
Borneol is more thermodynamically stable. Isoborneol is the kinetic product.

Yes, passive diffusion is a spontaneous process.

Thermodynamically stable means that a system is in a state where its energy is at a minimum and it is in equilibrium. This state is achieved when the system has reached its lowest energy level and is not easily disturbed. A thermodynamically stable system is less likely to undergo spontaneous changes or reactions, making it more stable overall.
The aim of electrolysis is to use an electric current to bring about a non-spontaneous chemical reaction, typically to separate compounds into their constituent elements or to produce desired products through redox reactions at the electrodes.
Favorable chemical reactions are those that release energy, produce a decrease in entropy, or result in the formation of more stable products. These reactions typically proceed in the direction of equilibrium and are thermodynamically spontaneous. Examples include combustion reactions and exothermic reactions.
Enthalpy change is not the only consideration for whether a reaction is favorable. However, if the enthalpy change is large, it is usually the dominant factor in determining favorability. Therefore, reactions that have a large, negative tend to be favorable, because the reaction usually releases energy when it occurs. Reactions that have a large, positive tend to be unfavorable as written, because the reaction usually requires energy to occur.
When a chemical reaction is described as being "thermodynamically favored," it means that it requires a great deal of activation energy for it to occur.
The result of electrolysis is the separation of a molecule in ions: cations and anions.
No, not all irreversible reactions are spontaneous - for example, cooking an egg. Once it's cooked, there's no going back to the raw egg stage. But it takes a lot of heat to get to that stage, so it is not spontaneous. If you find an old egg laid by a hen, it will not have a hardboiled texture!
An outside source of energy is needed for electrolysis to overcome the activation energy barrier and drive the non-spontaneous redox reactions that occur during the process. This energy is required to separate the ions in the electrolyte solution and facilitate the transport of charges towards the electrodes for the desired chemical reactions to take place.
Then use electrolysis to transfer all the copper from the impure anode to the cathode.
Endothermic reactions require an input of energy to proceed, which means they do not occur spontaneously. Spontaneous reactions release energy to their surroundings, unlike endothermic reactions that absorb energy from the surroundings. Therefore, endothermic reactions cannot be spontaneous as they need an external energy source to drive the reaction forward.
Redox reactions can occur in electrolytic cells when an externally applied electrical current drives non-spontaneous redox reactions to proceed. This is a process used in electrolysis, where an electrical current is passed through an electrolyte to induce chemical changes.
