The activation energy is the amount of energy needed to start a reaction. If the reactants have less than that amount the reaction will not occur. In this way it acts as a barrier that prevents a reaction unless there is enough energy to break it.

∙ 15y agoActivation energy of a reaction acts as a barrier because if there is not a certain amount of energy, the reaction can't start. Imagine a reaction as being you climbing over a 10 foot wall with a ladder. The 10 feet represents the activation energy, because you have to have a 10 foot ladder to get to the top. If you have a short ladder, you cannot get to the top, much like if you don't have enough activation energy, you can't have a reaction.

Can enzymes increase the rate of chemical reaction by lowering activation energy barriers?
That's the way they do it
What is the minimum amount of energy needed to start a chemical reaction?
activation energy ( I know it is right because it is in my science book)
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
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.
Can enzymes increase the rate of chemical reaction by lowering activation energy barriers?
That's the way they do it
What would happen if activation energy barriers didn't exist?
All chemical reactions in the body would proceed whether they were needed or not.
What is the minimum amount of energy needed to start a chemical reaction?
activation energy ( I know it is right because it is in my science book)
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.
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 kind of energy do enzymes reduce?
activation energy activation energy
Do enzymes work by providing energy to initiate reaction?
No they do not supply energy to start a chemical reaction, however energy has something to do with it. Enzymes actually lower energy barriers, in other words it reduces the activation energy needed which is the energy absorbed before the chemical reaction can start.
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 does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
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 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.
