Question

Threshold energy is equal to:
A) Activation energy
B) Activation energy – energy of molecules
C) Activation energy + energy of molecules
D) None of these

Answer 1

Hint: We have to remember that the chemical kinetics is one of the topics used to study the kinetics nature of the chemical reaction. It is used to optimize the chemical reaction for industrial purposes. The reactant to the product so many parameters are required. All are optimised by using this chemical kinetics. Chemical kinetics is used as a mechanism of reactant to product in the chemical reaction.

Complete answer:
We have to know that the activation energy of a reaction is nothing but the amount of energy required for collision of reactant molecules in chemical reactions.
Activation energy = Threshold energy - energy of molecules
Colloidal molecules have a minimum amount of energy to complete the reaction that energy is called as threshold energy.
We can change our concern
Threshold energy = Activation energy + energy of molecules
From the above discussion we conclude,
Threshold energy = Activation energy + energy of molecules
Option A is not correct because threshold energy is not equal to Activation energy
Option B is not correct because threshold energy is not equal to Activation energy – energy of molecules
Option C is correct because threshold energy is equal to Activation energy + energy of molecules
Option D is not correct because none of these is not correct because option C is correct.

Note:
We must have to know that the rate of the reaction is an important factor for the study of reaction. The rate of reaction is an important concept for chemical kinetics. Rate of the reaction depends on the concentration of the reactant. The rate of reaction is also calculated by using the concentration of the product in the chemical reaction. Depending on the concentration, the sign of the rate will change.
