What is the minimum amount of energy needed to start a chemical reaction?
The minimum amount of energy needed to start a chemical reaction is called the activation energy. It is the energy required to break the bonds in reactant molecules and initiate the reaction. Once this energy barrier is overcome, the reaction proceeds without additional energy input.
Energy required to start chemical reaction?
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.
Why do reactions require activation energy?
Activation energy is needed to overcome the energy barrier and initiate a chemical reaction. It ensures that reactant molecules have enough energy to break existing bonds and form new ones. Without activation energy, reactions would not proceed efficiently or may not occur at all.
What term is used to describe the minimum amount of energy required in order for a reaction to proceed?
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a 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.
What would an enzyme do in a cell?
it lowers activation energy.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

What is the minimum energy required for molecules to react with each other called?
That is called the activation energy or energy of activation (Ea).
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.
Why is reaching activation energy necessary?
Reaching activation energy is necessary because it determines the minimum energy required for a chemical reaction to occur. This energy allows reactants to overcome the energy barrier and transform into products. Without sufficient activation energy, collisions between molecules would not have enough energy to break bonds, preventing the reaction from proceeding. Thus, activation energy is crucial for initiating and facilitating chemical reactions.
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 term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
