Q. The unit of rate constant of second order reaction
A) $time^{- 1}$
B) $conc^{- 1}time^{- 1}$
C) $conc\ time^{- 1}$
D) $conc^{- 2}time^{- 1}$
Explanation
(b)
For $nth$ order reaction the unit of k is expressed as
$conc.^{(1 - n)}time^{- 1}$
Hence ,for second order ,the unit of rate constant is as
$conc.^{(1 - 2)}time^{- 1}$
$conc.^{- 1}time^{- 1}$
