$t = \frac{0.693}{k}$

$t = \frac{6.909}{k}$

$t = \frac{4.606}{k}$

$t = \frac{2.303}{k}$

Explanation

To solve this problem, we need to determine the time required for the completion of $99\%$ of a first-order reaction. $\newline$ For a first-order reaction, the integrated rate equation is given by: $\newline \ln \left( \frac{[A]_0}{[A]} \right) = kt \newline$
