For a first order reaction half life is ...

For a first order reaction half life is 14 sec. The time required for the initial concentration to reduce 1/8 of the value is

A

`(14)^(3)sec`

B

28 sec

C

42 sec

D

`(14)^(2) sec`

Text Solution

Verified by Experts

The correct Answer is:
C
`a overset(14sec)(rarr)(a)/(2)overset(14 sec)(rarr)(1)/(4)overset(14 sec)(rarr)(1)/(g)`
Total time taken = 42 sec.
