. What is threshold energy

Best Answer

Explanation :

Threshold energy is a term associated with commencement of a chemical reaction.

It can be defined as the minimum amount of energy that a substance/compound must possess in order to be able to proceed a reaction,undergo effective collision,

go through its transition state and finally form a product. 

For any chemical reaction to proceed, the reactants need to possess this bare minimum energy i.e. threshold energy. 

Threshold energy can be represented with the help of this graph :


Final Answer :

Thus,threshold energy is defined as the bare minimum energy that a molecule undergoing a chemical reaction needs to possess

in order to be able to undergo effective collision and transform to an activated complex that is capable of forming a product.
