1.	What is an elementary reaction? Give the differences between order and molecularity of a reaction.
Answer» Elementary reaction – Each and every single step in a reaction mechanism is called an elementary reaction. Differences between order and molecularity: Order of a reaction: 1. It is the sum of the powers of concentration terms involved in the experimentally determined rate law. 2. It can be zero (or) fractional (or) integer. 3. It is assigned for a overall reaction. Molecularity of a reaction: 1. It is the total number of reactant species that are involved in an elementary step. 2. It is always a whole number, cannot be zero or a fractional number. 3. It is assigned for each elementary step of mechanism.

Elementary reaction – Each and every single step in a reaction mechanism is called an elementary reaction.

Differences between order and molecularity: Order of a reaction:

1. It is the sum of the powers of concentration terms involved in the experimentally determined rate law.

2. It can be zero (or) fractional (or) integer.

3. It is assigned for a overall reaction.

Molecularity of a reaction:

1. It is the total number of reactant species that are involved in an elementary step.

2. It is always a whole number, cannot be zero or a fractional number.

3. It is assigned for each elementary step of mechanism.
