List the Various Differences Between Order and Molecularity of a Reaction

Answer: 

 

Sr. No.

Order of the reaction

Molecularly of the reaction

1.

The sum of the powers to which the concentrations of the reactants are raised, in the rate law of the equation, is called the order of the reaction.

It is the number of molecules or ions that take part in the rate-determining step.

2.

It can be a fractional, whole number or zero

It is always a whole number

3.

It can be only experimented with and not calculated

It can be calculated just by adding the molecules in the reaction

4.

It is derived from the rate of reaction

It is derived from the mechanism of the reaction

5.

It can be applied for all chemical reactions

It is only applied for simple reactions
