Question

List the various differences between Order and Molecularity of a reaction

Answer 1

Making the differences between order and molecularity:

Order	Molecularity
Order of a reaction refers to the exponential power raised to the concentration of product in a rate law expression.	Molecularity refers to the simultaneous collision of two or more than two particles while reacting.
Order can be fractional, natural number, or whole number.	Molecularity is always a natural number.
Order can be Zero	Molecularity of a reaction cannot be zero
The order of a reaction is determined by experimental methods.	The Molecularity of a reaction is determined by observation of the reaction.
