Question

hii guys plzz define threshold energy......​

Answer 1

Answer:

What is meant by threshold energy?

In particle physics, the threshold energy for production of a particle is the minimum kinetic energy a pair of traveling particles must have when they collide. The threshold energy is always greater than or equal to the rest energy of the desired particle.

What is threshold energy in chemical kinetics?

The threshold energy is the minimum energy required for the reactants to collide successfully, and to form the activated complex. It is kinetic energy plus energy of activation. Hence, threshold energy is greater than activation energy.

Definition of Threshold Energy

Threshold energy is the minimum kinetic energy the molecules must have to bring about effective collisions between two reactant molecules considered as hard spheres, resulting in a chemical reaction.

Therefore,

Threshold energy= Average of the initial kinetic energy possessed by the reactants + Activation energy (Ea)

If the reactants at the start of the reaction have sufficient energy for the collisions, then the threshold energy is equal to the activation energy (Ea).
