Q. In the following reaction $A \rightarrow B + C,$ rate constant is $0.001\ {Ms}^{- 1}.$ Half-life and completion time of the given reaction are
A) 500 s, 1000 s
B) 500 s, 750 s
C) 250 s, 500 s
D) 300 s, 600 s
Explanation
(a)
$A \rightarrow B + C$
$t_{1/2} = \frac{a}{2k} = \frac{1}{2 \times 0.001} = 500\ s$
And $T = \frac{a}{k} = \frac{1}{0.001} = 1000\ s$
