No. A spontaneous reaction is one that will happen given enough time - it doesn't need any energy or enzyme to make it happen. For instance, the decomposition of carbonic acid (H2CO3) into water and carbon dioxide (H2O and CO2) is spontaneous. However, it can be reversed by an enzyme called carbonic anhydrase; it just takes energy.
A spontaneous chemical reaction is one that occurs without requiring an external input of energy to proceed. The rate of a reaction, however, is determined by the activation energy needed for the reaction to occur. So, a spontaneous reaction can still be slow if the activation energy is high, meaning the reaction rate is low.

What does the term spontaneous mean in a chemical reaction?
Spontaneous in a chemical reaction means that the reaction occurs naturally without any external influence once started. It is driven by the inherent properties of the reactants and products, leading to a decrease in free energy and an increase in entropy.
What does the term spontaneous mean in chemical reactions?
This is a very fast reaction.
What is a chemical reaction that gets hot?
One example of a chemical reaction that releases heat is the combustion of a fuel like gasoline in air to produce carbon dioxide and water vapor. This reaction releases energy in the form of heat and light.
The information not provided by a chemical equation?
A chemical equation does not provide information about the physical state of the substances (solid, liquid, gas, or aqueous) involved in the reaction, the reaction conditions (temperature, pressure, catalyst), the rate of the reaction, the mechanism of the reaction, or any side reactions that may occur. This additional information is often necessary to fully understand and describe a chemical reaction.
What is a reaction rate apex?
The reaction rate apex is the point of maximum reaction rate in a chemical reaction. It represents the fastest rate at which reactants are being converted into products. This point is often used to optimize reaction conditions for maximum yield or efficiency.

Is sublimation fast reaction?
Not necessarily.
How do you use fast laser to measure the react time on chemical reaction?
The pulses on the fast laser will enable us measure the reaction time on the chemical reaction.
What is a fast exothermic chemical reaction?
Fireworks
What is the measurement of how fast a chemical reaction happens after it is started called?
reaction rate
Is an explosion a slow or fast chemical reaction?
An explosion is a fast chemical reaction that occurs rapidly, leading to the sudden release of energy, gases, and heat. This rapid reaction results in a quick expansion of gases and a sudden increase in pressure, causing the explosion.
Are explosions a physical change or a chemical change?
Chemical, an explosion is essentially extremely fast combustion which is a chemical reaction.
How do you tell how fast a chemical reaction will take?
Only after the measurement of the reaction rate. See the link below for details.
How nuclear decay rates different from chemical reaction rates?
nuclear decay rates take more time and chemical reaction rates could happen fast.
Do stoichiometry problems involve predicting how fast a reaction will occur?
No. Stoichiometry studies the quantities involved in chemical reactions. How fast a reaction occurs is a branch of chemistry called kinetics.
What things can be done to change how fast a chemical reaction occurs?
You can add a catalyst, or raise the temperature, or change the pressure, these are some of the things done to speed up a chemical reaction.
