Question

The unit of rate constant for the second order reaction will be ___________

(a) s^-1

(b) L mol^-1 s^-1

(c) Mol^0.5 L^-0.5 s^-1

(d) Mol L^-1 s^-1

The question was posed to me during a job interview.

The doubt is from Order of a Reaction topic in portion Reaction Dynamics of Engineering Chemistry I

Answer 1

Right option is (c) Mol^0.5 L^-0.5 s^-1

For explanation I would say: The unit of rate constant for the second order reaction will be mol^0.5 L^-0.5 s^-1.
