NEET Chemistry Chemical Kinetics Questions Solved

BOARD

Write two differences between 'order of reaction' and 'molecularity of reaction'.

Order of reaction:

(i) It is the sum of the concentration terms on which the rate of reaction actually depends.

(ii) It can be fractional as well as zero.

Molecularity of reaction:

(i) It is the number of atoms, ions or molecules that must collide with one another simultaneously so as to result into a chemical reaction.

(ii) It is always a whole number.
