What are the units of the rate constant k for a zero-order reaction?
A.M*s^-1
B.s^-1
C.M^-1*s^-1
D.M*s
Explanation
Core Concept
Zero order means rate = k[A]^0 = k, so the rate constant carries the units of rate itself. Rate is expressed in molarity per second, or Ms^-1. Each overall order changes the units of k so that k multiplied by the concentration terms always yields Ms^-1. For zero order nothing multiplies k, so it must supply the full rate units alone.
Correct Answer
AM*s^-1
