WebOct 4, 2024 · Many reactions have the order of reaction different from the molecularity of the reaction. This case is mainly when one reactant is present in significant excess. Examples are Hydrolysis of ethyl acetate and inversion of cane sugar in an aqueous solution. Above reaction, the molecularity of each reaction is two, and the order of a reaction is one. WebMolecularity refers to the amount of distinct molecules involved in a reaction while order refers to the exponent to which the concentration terms are raised to obtain the rate of reaction. A unimolecular reaction isn't exactly a "reaction" if you look through common sense, as a single reactant cant actually "react" with anything.
