WebApr 9, 2024 · Molecularity and order of reaction both give information about the chemical reaction but are very different from each other as one tells about the number of molecules taking part in reaction while another one tells about the relationship between rate of reaction and concentration of reactants. WebOrder of a reaction is the sum of the concentration of the reactant on which the rate of reaction depends primarily. Molecularity is the number of reacting molecules, such as atoms, which collide and result in a chemical reaction. Both order of reaction and molecularity are important terms in chemical kinetics.

Molecularity Overview & Examples What is Molecularity?

WebS. N. Molecularity. Order of reaction. 1. It is the total number of reacting species that must simultaneously collide together to bring about a change in the chemical reaction. The concentration’s exponent or power for a specific reactant as specified in the law of rate determines the order of a reaction. 2. WebFeb 22, 2024 · What is Order of Reaction 3.
