What are the units of rate constant for the first order reaction?

Rituraj Tiwari

LetRbe the rate of reaction.
For first order reaction,
R=K[A]1
⇒K=R[A]^−1
Whereas,Kand[A]are rate constant and initial concentration of reactant respectively.
Therefore,
Unit of rate constant=(molL−1)^(1−n)sec−1
For first order reaction,
n=1
Unit of rate constant=sec−1
Hence 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]1
Whereas, K and [A] are rate constant and initial concentration of reactant respectively.
Therefore,
Unit of rate constant =(molL1)1nsec1
For first order reaction,
n=1
Unit of rate constant =sec1
Hence the unit of rate constant for first order reaction is sec1.
