Consider a reaction, `2A + B rarr` Products
When concentration of `B` alone was doubled, the half-life did not change. When the concentration of `A` alone was doubled, the rate increased by two times. The unit of rate constant for this reaction is :

A

`s^(-1)`

B

lit.`"mol"^(-1)s^(-1)`

C

Unitless

D

mol.`"lit"^(-1)s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A

`r=K[A]^(1)[B]^(0)` First order: unit of `K = sec^(-1)`
