The unit for specific reaction rate "(K)" of second order reaction is

Specific reaction rate for the first order reaction depends upon

The unit of rate constant for a second order reaction is

Assertion (A) : The rate constant of a pseudo unimolecular reaction has the units of a second order reaction. Reason (R ): A pseudo unimolecular reaction is a reaction of second order in whiich one of the reactant is present in large excess.
