If the concentration is expressed in mol dm^(-3) and time in seconds, the unit of the rate constant for a first-order reaction will be

Answer»

MOL `DM^(-3)s^(-1)`
`s^(-1)`
`dm^(3)mol^(-1)s^(-1)`
`dm^(-3)mol^(-1)s^(-1)`

SOLUTION :For a first order REACTION,
`dx/dt=k[A]`
`k=("mol "dm^(-3) s^(-1))/("mol "dm^(-3))=s^(-1)`
