A pseudo unimolecular reaction has order of reaction ?
Answers
Answer:
A Pseudo first-order reaction can be defined as a second-order or bimolecular reaction that is made to behave like a first-order reaction. This reaction occurs when one reacting material is present in great excess or is maintained at a constant concentration compared with the other substance.

Answer:
Molecularity in chemistry is the number of molecules that come together to react in an elementary (single-step) reaction[1] and is equal to the sum of stoichiometric coefficients of reactants in this elementary reaction.[2] Depending on how many molecules come together, a reaction can be unimolecular, bimolecular or trimolecular.
The kinetic order of any elementary reaction or reaction step is equal to its molecularity, and the rate equation of an elementary reaction can therefore be determined by inspection, from the molecularity.[1]
The kinetic order of a complex (multistep) reaction, however, cannot be equated to molecularity since molecularity only describes elementary reactions or steps.
