Spontaneous reactions occur slowly due to kinetic barriers such as high activation energy, which must be overcome for reactants to transform into products. While the thermodynamic driving force may favor the reaction, the rate at which it proceeds is influenced by factors like molecular collisions and the need for specific orientations. Additionally, some reactions require intermediates or specific conditions that can further delay the process. Therefore, even thermodynamically favorable reactions can be sluggish without an appropriate catalyst or environmental conditions.
What else can I help you with?
What are differences between rapid and spontaneous combustion?
The spontaneous combustion flows very slowly and occur by self heating.
Why do many spontaneous reactions occur very slowly and theu don't occur instantly?
a. all reactions are endergonicb. many reactions require large inputs of activation energyc. no catalysts are present in body cellsd. there is not enough ATP in body cells
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
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.
What reaction is the most spontaneous?
The most spontaneous reaction is typically a reaction that releases a large amount of energy in a short period of time, such as explosions or combustion reactions. These reactions occur quickly and without requiring an external force to initiate them.
Is the reaction spontaneous or non-spontaneous when considering the keyword "spontaneous vs non-spontaneous"?
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.
What is the reverse of a spontaneous reaction, and how does it differ from a nonspontaneous reaction?
The reverse of a spontaneous reaction is a nonspontaneous reaction. In a spontaneous reaction, the reaction occurs naturally without any external influence, while in a nonspontaneous reaction, external energy input is required for the reaction to occur.

What factor might make an endothermic reaction spontaneous?
An endothermic reaction can be spontaneous if the increase in entropy (disorder) of the system is large enough to overcome the energy input required for the reaction to occur.
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.
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
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.
The synthesis of decomposition of nitrogen dioxide is endothermic and nonspontaneous at room temperature what must be true regarding this reaction?
For the reaction to occur at room temperature, an external energy source must be provided to drive the reaction, and the reaction will absorb heat from the surroundings. The reaction is non-spontaneous because it does not occur naturally without intervention.
What reaction is the most spontaneous?
The most spontaneous reaction is typically a reaction that releases a large amount of energy in a short period of time, such as explosions or combustion reactions. These reactions occur quickly and without requiring an external force to initiate them.
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.
