Starting with one mole of a compound A, ...

Starting with one mole of a compound `A`, it is found that the reaction is `3//4` completed in `1 hr`. Find the rate constant if the reaction is of `II` order.

A

`2.31 "min"^(-1)`

B

`0.231 "min"^(-1)`

C

`0.0231"min"^(-1)`

D

`0.00231 "min"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`k=(2.303)/(t)log.(a)/(a-x)`
`k=(2.303)/(60)log.(1)/(1-3//4)`
`k=(2.303)/(60)log.4=0.0231`
