What are the units of the rate constant of a pseudo unimolecular reaction ?

Verified by Experts

`k'=k[H_(2)O]:.(k')/([H_(2)O])=(min^(-1))/(molL^(-1))=Lmol^(-1)min^(-1)`
Thus, it has the units of a second order reaction.

In pseudo-unimolecular reactions :

one of the reactants is present in large excess

both reactants have some concentration

both the reactants are present in low concentration

one of the reactants is less reactive

the molecularity and order of a reaction is one

the molecularity of the reaction is one while their order is zero

two reacting speies are involved in the rate determining step

the molecularity and order of the slowest step of the reaction is euqal to one
