Q. For a reaction, the rate constant is $2.34s^{- 1}.$ The half-life period for the reaction is
A) 0.30 s
B) 0.60 s
C) 3.3 s
D) Data is insufficient
Explanation
(a)
Given that, $k = 2.34s^{- 1}$ unit of ‘k’ suggest that the reaction is of Ist order , hence for Ist order reaction,
$t_{1/2} = \frac{0.693}{k}$
$= \frac{0.693}{2.34}$
=0.30 s
