Best Answer

Energy required for a reaction can vary. Depending on the atom it changes. The element will be more reactive if it has a low 1st ionization energy since it requires less energy to react. The most reactive element in Francium since it has the lowest 1st ionization energy level. If an element has a high electro-negativity then it will also be able to react with little energy.

The energy required to start a chemical reaction is known as activation energy. This energy is needed to break the bonds in the reactant molecules before new bonds can form in the products. Activation energy acts as a barrier that must be overcome for the reaction to proceed.

That is the function of a catalyst.


Start up energy of a chemical reaction?

The activation energy is the minimum amount of energy required to initiate a chemical reaction. It helps to break the existing bonds in reactant molecules and start the formation of new bonds in the product molecules. Lowering the activation energy can increase the reaction rate.


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.


The amount of energy required to start a reaction is called?

The amount of energy required to start a reaction is called activation energy. It is the energy needed to initiate a reaction by breaking the chemical bonds of the reactants.


Which term describes energy that is required to get chemical reactions started?

Activation energy is the term used to describe the energy required to start a chemical reaction by breaking the initial bonds between atoms or molecules. This energy barrier must be overcome in order for the reaction to proceed.


Energy needed to kick start a reaction is called what?

The energy needed to kick start a reaction is called activation energy. It is the minimum amount of energy required for a chemical reaction to occur. It is usually provided in the form of heat or light energy.


What is proteins that reduce the amount of energy needed to start a chemical reaction are called?

Proteins that reduce the amount of energy needed to start a chemical reaction are called enzymes. Enzymes act as catalysts by lowering the activation energy required for a reaction to occur, thus speeding up the reaction.


Which is the best description of activation energy?

Activation energy is the minimum amount of energy required for a chemical reaction to occur. It is needed to initiate the reaction by breaking the bonds of the reactant molecules.
