For a first order reaction the rate constant for decomposition of `N_(2)O` is `6xx10^(-4)sec^(-1)`. The half-life period for the decomposition in seconds is :

A

11.55

B

115.5

C

1155

D

1.155

Text Solution

Verified by Experts

The correct Answer is:
C
`t_(1//2)=(0.693)/(K)`
`=(0.693)/(6xx10^(-4))`
`=(693xx10^(3))/(6xx10^(-4))=1155sec`
