The half life of a first order reaction ...

The half life of a first order reaction having rate constant `k=1.7xx10^(-5) sec^(-1)` is :

A

12.1 h

B

9.7 h

C

11.3 h

D

1.8 h

Text Solution

Verified by Experts

The correct Answer is:
c

k = `1.7 xx 10^(-5) s^(-1)`
`t_(1//2) = (0.693)/(k) = (0.693)/(1.7) xx 10^(5) = 11.32` h.
