In a certain reaction, `10%` of the reactant decomposes in one hour, `20%` in two hours, `30%` in theee hours, and so on. The dimenison of the velocity constant (rate constant) are

A

`"hour"^(-1)`

B

`"mole litre"^(-1) sec^(-1)`

C

`" litre mole"^(-1) sec^(-1)`

D

`"mole sec"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B

It is zero order reaction therefore units of K is mol `L^(-1) s^(-1)`
