What is activation energy how is the rate constant of a reaction related to its activation energy?
In chemistry, activation energy is a term introduced in 1889 by the Swedish scientist Svante Arrhenius that means the minimum energy that must be input to a chemical system with potential reactants to cause a chemical reaction. Activation energy may also be defined as the minimum energy required to start a chemical reaction.The activation energy of a reaction is usually denoted by Ea and given in units of kilojoules per mole

What does it mean if the activation energy is high related to traveling?
If the activation energy elated to travelling is high, then a large amount of energy is required to start a chemical reaction. After the reaction is initiated, less energy is needed.
What it the term used to describe the energy needed to get a reaction started?
The energy needed to get a reaction started is called activation energy.
What is activation energy How does a catalyst affect activation energy?
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
According to the Arrhenius equation what factor will affect the rate constant?
According to the Arrhenius equation, the rate constant (k) is affected primarily by temperature and activation energy (Ea). As temperature increases, the rate constant typically increases due to more molecules having sufficient energy to overcome the activation barrier. Additionally, a lower activation energy leads to a higher rate constant, as it requires less energy for the reaction to proceed. Thus, both temperature and the nature of the reaction (reflected in Ea) significantly influence the rate constant.
How does activation energy affect the progress affect the progress of a reaction?
The reaction will not occur unless the activation energy is met.
What is the relationship between the rate constant of a reaction and the activation energy of the reaction?
The rate constant of a reaction is directly related to the activation energy of the reaction. A higher activation energy typically results in a lower rate constant, meaning the reaction proceeds more slowly. Conversely, a lower activation energy usually leads to a higher rate constant, indicating a faster reaction.
What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
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.
Can a reaction have zero activation energy?
No, all reactions require some activation energy to proceed, even if it is very small. Activation energy is the minimum amount of energy required for reactant molecules to transform into product molecules.
How does activation energy affect chemical reactions?
The Arrhenius equation is: Ea = -RT ln(k/A) where Ea - activation energy R - universal gas constant ln - logarithm k - speed constant T - temperature in kelvins
What does it mean if the activation energy is high related to traveling?
If the activation energy elated to travelling is high, then a large amount of energy is required to start a chemical reaction. After the reaction is initiated, less energy is needed.
How temperature related to activation energy?
The relation is:k is the reaction rate coefficient.
What it the term used to describe the energy needed to get a reaction started?
The energy needed to get a reaction started is called activation energy.
Is activation energy added or just there?
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.
What is activation energy How does a catalyst affect activation energy?
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What is the relationship between an energy diagram and activation energy in a chemical reaction?
An energy diagram shows the energy changes that occur during a chemical reaction. Activation energy is the minimum amount of energy required for a reaction to occur. In the energy diagram, the activation energy is the energy barrier that must be overcome for the reaction to proceed. A higher activation energy means a slower reaction, while a lower activation energy means a faster reaction.
