What is the energy needed to break existing chemical bonds during the initiation of a chemical reaction?
Wiki User

The energy needed to break an existing chemical bond is called activation energy, also written as Ea
Activation energy can be decreased with the help of a catalyst, which helps to facilitate chemical reactions.

The energy needed to break existing chemical bonds during the initiation of a chemical reaction is called the activation energy. This energy is required to overcome the energy barrier between reactants and products, allowing the reaction to proceed. Once the activation energy is reached, the bonds can be broken and new bonds can form.

Definition of activation energy
The minimum extra amount of energy absorbed by the reactant molecule so that their energy becomes equal to threshold value is called activation energy.
This activation energy not only used for break preexisting bond it's also used to create new bonds in products.

What is the starting substance in a chemical reaction is?
The substances you have at the beginning of a chemical reaction are called the reactants.
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
Is energy absorbed or released during a decomposition reaction?
Energy is often absorbed during a decomposition reaction because the reactant breaks down into smaller molecules or atoms. This process typically requires energy input to break the existing chemical bonds.
What is the scientific word for a gas given off during a chemical reaction?
The scientific word for a gas given off during a chemical reaction is "effluent".
What are the steps to a chain reaction?
A chain reaction typically involves three steps: initiation, propagation, and termination. During initiation, the reaction is triggered by an initial event. In propagation, products from the initial reaction continue to react, creating more products. Termination occurs when the reaction eventually stops due to the depletion of reactants or other factors.
When new substances are formed from existing substances during a chemical reaction they are known as?
Products.
What happens to chemical bonds in a molecule during a chemical reaction?
The existing chemical bonds break and new bonds are created to give products.
What happens chemical bonds during a chemical reaction?
Some or all of the existing chemical bonds in the reactants are broken and new chemical bonds are formed in the products.
What happens to the atoms of an object or a substance during a chemical reaction?
The atoms involved in a chemical reaction have their bonds broken, new bonds formed, or existing bonds rearranged depending on the reaction type.
What happens to energy during a chemical reaction?
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
What is always formed during a chemical reaction?
a chemical reaction always converts reactants to products. Products are always formed otherwise it's not considered a chemical reaction.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
What is the starting substance in a chemical reaction is?
The substances you have at the beginning of a chemical reaction are called the reactants.
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What happens to the bonds of the products during a chemical reaction?
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
