Question

For a reaction of order n, the unit of the rate constant is ______.

पर्याय

• mol^1-n L^1-n s

• mol^1-n L²ⁿ s^-1

• mol^1-n L^n-1 s^-1

• mol^1-n L^1-n s^-1

Answer 1

For a reaction of order n, the unit of the rate constant is mol^1-n L^n-1 s^-1.

Explanation:

Rate = k[A]ⁿ

comparing units

`(("mol"//"L"))/"sec" = "k"("mol"/"L")^"n"`

`=> "k" = "mol"^(1 - "n") "L"^("n - 1")"s"^(- 1)`
