The information from diagram shows the energy requirements needed in order for a reaction to
occur.
What is Collision theory?
The collision theory states that each and every chemical reaction can occur between particles when the molecules collide each other.
The collision between particles is necessary but it is not sufficient for a reaction to take place. The collisions must be effective.
It is necessary to know the exact nature of an effective collision since this indicates whether particles react with each other and form new products.
According to collision theory, the reaction occur when molecules collide and molecules have sufficient activation energy to cross energy barrier.
Greater the energy, greater will be number of collision. Lesser energy, lesser will be number of collision.
Thus, the given energy diagram shows about the energy required for a reaction to take place.
