A reaction is considered non-spontaneous when the Gibbs free energy change (ΔG) is positive, indicating that the reaction requires an input of energy to occur. This could happen when the reactants have high energy relative to the products or when the reaction conditions do not favor the formation of products.
spontaneous
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.
Non-spontaneous processes require intervention or energy input to occur, while spontaneous processes occur on their own without needing external help. Spontaneous processes tend to move towards equilibrium, while non-spontaneous processes move away from equilibrium.
Spontaneous monologue refers to an unplanned, impromptu speech where the speaker expresses thoughts or emotions in the moment, often reflecting genuine feelings or reactions. In contrast, a non-spontaneous monologue is premeditated and rehearsed, typically involving a structured presentation of ideas or narratives. While spontaneous monologues can convey authenticity and immediacy, non-spontaneous ones tend to prioritize clarity and coherence. Both serve different purposes in communication, depending on context and audience.

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 uniform mixing of bromine vapor and nitrogen gas is a non-spontaneous process because it requires an input of energy to overcome the entropy-driven tendency of the two components to remain separated due to differences in their properties.
The units of Gibbs energy are joules (J) or kilojoules (kJ). Gibbs energy is related to the thermodynamic properties of a system by indicating whether a process is spontaneous or non-spontaneous. If the Gibbs energy is negative, the process is spontaneous, and if it is positive, the process is non-spontaneous.
Electrolytic cell
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.
