Question

how to determine the unit of rate constant of a reaction​

Answer 1

Answer:

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 =(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 is sec

−1

.
