Non spontaneous means that when you say in chemical terms, mix two different substances together, they don't react to form something new. A counter example to this is baking soda and vinegar. If you mix them together, they will spontaneously react to produce carbon dioxide. Non spontaneous processes require some form of energy input in order to all the reaction to occur.
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
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 a spontaneous reaction, the change in Gibbs free energy (ΔG) is negative, indicating that the reaction can occur without the input of external energy. This negative value reflects a decrease in the system's free energy, driving the reaction forward toward equilibrium. A positive ΔG, on the other hand, suggests that the reaction is non-spontaneous and requires energy input to proceed.
To determine if a reaction is spontaneous or non-spontaneous at 298 K, we can use the Gibbs free energy equation, ΔG = ΔH - TΔS. If ΔG is negative, the reaction is spontaneous; if ΔG is positive, it is non-spontaneous. The values of ΔH (enthalpy change) and ΔS (entropy change) must be known to evaluate the spontaneity at this temperature. Without specific values for ΔH and ΔS, we cannot definitively conclude the spontaneity.
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.
spontaneous redox reaction
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 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 first of two factors that determine whether a reaction is spontaneous or non-spontaneous is entropy. The second is energy. For a reaction to be spontaneous, it must have both of these factors.
Spontaneous ...Happens all by itself; typically unpredictableNon-spontaneous...You have to do something to make it happen.
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.
