Question

what is Molecularity?​

Answer 1

Answer:

The molecularity of a reaction is defined as the number of molecules or ions that participate in the rate determining step. A mechanism in which two reacting species combine in the transition state of the rate-determining step is called bimolecular.

Answer 2

Molecularity:- It is the total number of molecules, atoms or lons means those reacting species which are taking place in an elementary reaction is known as molecularity of that reaction.

Some additional Information:-

• 1. It is a theoretical quantity.

• 2. It can be an integer like 1, 2, 3 or 4 but it never can be negative or 0.

• 3. It is equal to the order in an elementary reaction.

• 4. While in the complex reaction it is defined seperately.

• 5. Total molecularity of complex reaction is considered as meaningless.

• 6. 3 is the maximum value of Molecularity in order.
