Achemical reaction takes place in which energy is absorbed arrange the characteristics of the reaction in order from start to finish

A chemical reaction in which energy is absorbed is known as an endothermic reaction. The characteristics of the reaction in order from start to finish is as follows:

1. Lower energy of reactants
2. Transition state
3. Higher energy of products

This implies that in an endothermic reaction, the products are less stable than the reactants.

Because it was a dramatically big guy

Particle exchange energy though elastic collision , hope this .
