Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of 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 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?

This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.


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.
