In the reaction 2H₂O → 2H₂ + O₂, water (H₂O) is more stable than hydrogen (H₂) and oxygen (O₂) under standard conditions. This is because water is a low-energy compound, while the products, hydrogen and oxygen gases, possess higher energy due to their molecular bonds. As a result, the formation of water from its elemental gases releases energy, indicating that water is the more stable product in this reaction.
What else can I help you with?
Is 2H2O2--2H2O O2 spontaneous?
The reaction 2H2O2 --> 2H2O + O2 is spontaneous because it results in the formation of more stable products with lower energy compared to the reactant hydrogen peroxide (H2O2). This indicates a decrease in Gibbs free energy (∆G<0) and the reaction can occur without requiring an external energy source.
Are endothermic reaction products stable?
It depends on a few things. If you mean thermodynamically stable, then no. The product of an endothermic reaction is higher in potential energy than the reactant(s) and will eventually release that energy and revert back (if it doesn't go on to some other product). If you mean kinetically stable, then maybe. It really depends on the relative energy of any intermediates formed in the conversion of reactant(s) to product(s). This relative energy is also known as activation energy. If the activation energy is high, then the product would be relatively stable. If the activation energy is low, then the product would not be stable.
What happens to the compound in a decomposition reaction?
A compound breaks down into two or more compounds or elements.Example: 2H2O = 2H2 + O2A compound breaks down into two or more compounds or elements.Example: 2H2O = 2H2 + O2
What is an energonic reaction?
It is the opposite of an exergonic reaction. An energonic reaction would be one where more energy is put into the reaction than what comes out of it (like endothermic), while exergonic has more output energy than input (like exothermic).
Why is an energy absorbing reaction or an energy releasing reaction more likely to be spontaneous?
To become spontanious,energy should be released.
Is 2H2O2--2H2O O2 spontaneous?
The reaction 2H2O2 --> 2H2O + O2 is spontaneous because it results in the formation of more stable products with lower energy compared to the reactant hydrogen peroxide (H2O2). This indicates a decrease in Gibbs free energy (∆G<0) and the reaction can occur without requiring an external energy source.
In an endothermic reaction are the products more or less stable than the reactants and explain your answer?
In an endothermic reaction, the products are generally less stable than the reactants. This is because the reaction absorbs heat from the surroundings to proceed, indicating that the products have higher potential energy than the reactants.
What type of reaction is 2H2O 2H2 plus O2?
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
Is the reaction product sodium chloride more or less stable than the reactants sodium metal and chlorine gas?
Sodium chloride (NaCl) is more stable than the reactants sodium metal and chlorine gas because it is a compound with a lower energy state than the individual elements. The formation of NaCl involves the transfer of electrons from sodium to chlorine, resulting in the more stable ionic compound.
What factors contribute to making a reaction exothermic?
Factors that contribute to making a reaction exothermic include the release of heat energy, formation of more stable products, and a decrease in the overall energy of the system.
What is an energy releasing reaction?
An energy-releasing reaction is a chemical reaction in which energy is released as a byproduct. This can happen when bonds are formed between atoms, leading to a more stable state with lower potential energy. Common examples include combustion reactions and certain types of exothermic reactions.
Why is the Exo product thermodynamically more stable than the other products in the reaction?
The Exo product is thermodynamically more stable than the other products in the reaction because it has a lower energy state, making it more favorable and less likely to revert back to its original form.
How is activation energy related to bond energy?
Activation energy is the minimum energy required for a chemical reaction to occur. It is related to bond energy because breaking chemical bonds and forming new bonds requires energy, which contributes to the activation energy of a reaction. Bonds with higher bond energy are more stable and require more energy to break, hence increasing the activation energy of the reaction.
Are endothermic reaction products stable?
It depends on a few things. If you mean thermodynamically stable, then no. The product of an endothermic reaction is higher in potential energy than the reactant(s) and will eventually release that energy and revert back (if it doesn't go on to some other product). If you mean kinetically stable, then maybe. It really depends on the relative energy of any intermediates formed in the conversion of reactant(s) to product(s). This relative energy is also known as activation energy. If the activation energy is high, then the product would be relatively stable. If the activation energy is low, then the product would not be stable.
What is a negative Gibbs free-energy value an indication of?
A negative Gibbs free-energy value indicates that a reaction is spontaneous, meaning it can proceed without requiring external energy input. It suggests that the products of the reaction are more stable than the reactants at the given conditions.
What happens to the compound in a decomposition reaction?
A compound breaks down into two or more compounds or elements.Example: 2H2O = 2H2 + O2A compound breaks down into two or more compounds or elements.Example: 2H2O = 2H2 + O2
What is the relationship between the activation energy, activated complex, and reaction rate as depicted on a graph?
On a graph, the activation energy represents the minimum energy required for a reaction to occur. The activated complex is the unstable intermediate state during a reaction. The reaction rate is influenced by the activation energy and the stability of the activated complex. A lower activation energy and a more stable activated complex typically result in a higher reaction rate.
