What is activation energy?

Answer 1

ily

Answer 2

"In chemistry, activation energy, also called threshold energy, is a term introduced in 1889 by the Swedish scientist Svante Arrhenius, that is defined as the energy that must be overcome in order for a chemical reaction to occur. Activation energy may otherwise be denoted as the minimum energy necessary for a specific chemical reaction to occur."

"Activation energy is the minimum amount of potential energy required to change reactants into products (the forward Ea), or products into reactants (the reverse Ea)"

Hope this is what you were looking for!

This describes what it is, but it may not help because I am not sure in what context you are looking for a definition...I see you put it in the green living category but I don't know how it is applied in green living.

Answer 3

it is the minimum energy to get a reaction to move in one direction, either forward or backward.  This energy is is lost unless you stop the reaction and the whole system stops.

SO, its not a renewable or free energy.
