The rate constant of `n^(th)` order has units :

A

`litre^(1-n)mol^(1-n)sec^(-1)`

B

`mol^(1-n)litre^(1-n)sec`

C

`mol^(1-n^2)litre^(n^2)sec^(-1)`

D

`mol^(1-n) litre^(n-1)sec^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
For an nth order reaction : rate = `k [conc.]^n`
`k = ("rate")/(["conc."]^n)`
Units of `k = (mol L^(-1)s^(-1))/((molL^(-1))^n)= mol^(1-n) L^(n - 1) s^(-1)`
