Activation Energy is the minimun amount of energy required for active collision or to reach threshold energy from their average energy. 
This is the amount of energy which must be added to an atomic or molecular system to allow a particular process to take place.
The threshold energy for production of a particle is the minimum kinetic energy a pair of traveling particles must have when they carry out endorgenic reaction.
