If the activation energy of a reaction is high, then it requires a large amount of energy to initiate the reaction. The situation arising when a spontaneous reaction has a large activation energy is similar to rolling a ball over a hill. At first, energy must be expended to move the ball to the crest of the hill (or, in the case of a reaction, impart enough energy to the molecules so that their bonds can be sufficiently weakened). However, once the ball is at the top of the hill, it rolls down on its own. This is analogous to the reforming of chemical bonds, which releases energy. High activation energies are typical when a reaction involves molecules whose bonds are strong.
A reaction with a higher activation energy requires more energy to initiate the reaction. In general, reactions involving the breaking of strong chemical bonds have higher activation energies compared to reactions involving weaker bonds.

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.
What term is used to describe the minimum amount of energy required in order for a reaction to proceed?
The term is activation energy. It is the energy needed to start a chemical reaction by breaking bonds in the reactant molecules.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What is a sentence using the word activation energy?
Activation energy is the minimum amount of energy required for a chemical reaction to occur.
What is the minimum amounth of energy required for a reaction occur?
The minimum amount of energy required for a reaction to occur is called the activation energy. This energy is needed to break the bonds in the reactant molecules and initiate the chemical reaction. Once the activation energy is overcome, the reaction can proceed on its own.
What represents the highest energy point on an energy diagram?
activation energy
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 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.
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.
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.
Which is a best definition of activation energy?
Activation energy is energy or power conducted that can be instantly activated for use when flick a light switch you used activation energy.
What term is used to describe the minimum amount of energy required in order for a reaction to proceed?
The term is activation energy. It is the energy needed to start a chemical reaction by breaking bonds in the reactant molecules.
What kind of energy do enzymes reduce?
Enzymes reduce activation energy, which is the energy required to start a chemical reaction. By lowering the activation energy, enzymes make reactions occur more readily and at a faster pace.
Is activation energy added or just there?
Activation energy is the energy needed to initiate a chemical reaction, it is not added to the system or the reaction itself. It acts as a barrier that molecules must overcome to convert into products.
How do enzymes work what do they lower?
Enzymes function when they lower the activation energy. That means it takes less energy for the reaction to work.
