The reaction `Ararr B` follows first order kinetics. The time taken for `0.8 mol` of `A` to produce `0.6 mol` of `B` is `1 hr`. What is the time taken for the conversion of `9.0 mol` of `A` to Product `0.675 mol` of `B` ?

A

1 hour

B

0. 5 hour

C

0.25 hour

D

2 hour

Text Solution

Verified by Experts

Time required to complete a difinite fraction `(0.6/(0.8)=0.75 and 0.675/0.9- 0.75)`
For a first order reaction is independent of initial concentration.
