How do you determine whether a reaction is spontaneous or non spontaneous?

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.

∙ 13y agoIf the requirements at the activation threshold are met, then it will be spontaneous. This means if the reaction has a negative delta G, there is a higher concentration of reactants and the reaction will occur spontaneously because the system wants to reach equilibrium. Once the system reaches equilibrium, the reaction is no longer spontaneous. Because metabolism is never at equilibrium, glycolosis will always be a spontaneous reaction.

Is candle burning a spontaneous or non spontaneous reaction?
Spontaneous
How can one determine if a redox reaction will be non-spontaneous?
The reduction potential plus oxidation potential is negative.
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
Forming a triacylglyceride from three fatty acids and glycerol...identify this reaction as either anabolic or catabolic endergonic or exergonic and spontaneous or non spontaneous.?
Anabolic, endergonic, non-spontaneous
Ask us anythingWhich of the following describes a nonspontaneous reaction?
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

What is the reaction in a fuel cell spontaneous and non spontaneous?
Spontaneous ...Happens all by itself; typically unpredictableNon-spontaneous...You have to do something to make it happen.

Endothermic

Is ice melting a spontaneous reaction?
Before we go into the details of whether melting of ice at a room temperature of 25 degree Celsius is spontaneous reaction or not, we first define the spontaneous and non-spontaneous reactions. Spontaneous Reaction, as you know, is a reaction that takes place on its own without an external force or other reaction to drive it e.g. rusting or iron nail, burning of wood etc. Non-Spontaneous Reaction is a reaction which cannot occur without the input of work from an external source. Such as charging of battery, as the electrons flow is required to charge it completely. Now replying to your question: First of all I think, though I am not sure, that heat doesn't transfer from ice to the room. Actually, heat transfers from room to the ice and that's how ice is caused to turn into liquid. The ice needs heat from the surrounding to have its molecules to jiggle (vibrate) and this shaking of ice molecules changes it into liquid. Remember, this reaction is physical, not chemical. From all I have studied and I know, I truly believe that the conversion of ice into liquid form is spontaneous reaction.
