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