Question

The unit of the rate constant of a zero-order reaction and second-order reaction is same.

(a) True

(b) False

The question was posed to me by my school principal while I was bunking the class.

The origin of the question is Chemical Kinetics in section Chemical Kinetics of Chemistry – Class 12

Answer 1

Right answer is (b) False

To explain I would say: The unit of the rate constant k for a zero-order reaction is mol L^-1 s^-1. For a first-order reaction, the unit of k is s^-1. The unit of the rate constant k for a second-order reaction is mol^-1 L s^-1.
