Order and Molecularity in engineering chemistry pdf free download
The principal process in experimental chemical kinetics is always to determine k, and. A special situation or simplification occurs when = and =, i.e., the stoichiometric coefficient of a variants equals the order to which the concentration of that species has to be brought up in eqn

The order of reaction with respect to a reactant is defined as the power (exponent) of the concentration of the reactant to which the rate of reaction is directly proportional. The overall order of reaction is the sum of all the exponents of all the reactants.
Molecularity on the other hand is defined as the number of reacting species (atoms, ions or molecules) taking part in an elementary reaction, which must collide simultaneously in order to bring about a chemical reaction.
Also, the order of a reaction is the same as its molecularity but the converse is not true.
