							LetRbe the rate of reaction.For first order reaction,R=K[A]1⇒K=R[A]^−1Whereas,Kand[A]are rate constant and initial concentration of reactant respectively.Therefore,Unit of rate constant=(molL−1)^(1−n)sec−1For first order reaction,n=1Unit of rate constant=sec−1Hence the unit of rate constant for first order reaction issec−1.

							Dear student Let R be the rate of reaction.For first order reaction,R=K[A]1⇒K=R[A]−1Whereas, K and [A] are rate constant and initial concentration of reactant respectively.Therefore,Unit of rate constant =(molL−1)1−nsec−1For first order reaction,n=1Unit of rate constant =sec−1Hence the unit of rate constant for first order reaction is sec−1.
