Question

Define threshold energy of a reaction.

Answer 1

Answer: 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.

Explanation:

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

Answer 2

Answer:

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
