For a first order reaction, if the time ...

For a first order reaction, if the time taken for completion of 50% of the reaction is t second, the time required for completion of 99.9% of the reaction is:

A

10t

B

5t

C

100t

D

2t

Text Solution

Verified by Experts

The correct Answer is:
A
`(Kxxt_(1))/(Kxxt_(2))=("log"100/50)/("log"100/0.1)impliest/(t_(2))=(log_(2))/(3log_(10)^(10)),t_(2)=(txx3)/0.3010=10xxt`
