The rate constant of the reaction A rarr...

The rate constant of the reaction `A rarr B` is `0.6 xx 10^(-3)` mole per second. If the concentration of `A` is `5 M`, then concentration of `B` after `20` minutes is:

A

1.08M

B

3.60M

C

0.36M

D

0.72M

Text Solution

Verified by Experts

The correct Answer is:
D
Key concept for a zero order reaction unit of rate constant is mole per second hence ,we can easily calculate concentration of B after 20 min by the following formula ,
x=Kt
x= kt =`0.6xx10^(-3)xx20xx60=0.72M`
