Rate constant in case of first order reaction is

A

inversely proportional to the concentration units

B

Independent of concentration units

C

directly proportional to the concentration units

D

inversely proportional to the square of the concentration units

Text Solution

Verified by Experts

The correct Answer is:
B
For a first order reaction
`k = (2.303)/(k)"log"([A]_(0))/([A])`
`therefore` Rate constant, k is independent of concentration units.
