If the rate constant for a first order reaction is $k$ , the time $(t)$ required for the completion of $99 %$ of the reaction is given byNEET 2019 (All India)

Options:

Answer:

Solution:

$k = \frac{2.303}{t} l o g \frac{a}{a - x}$

$a = 100$

$a - x = 100 - 99 = 1$

$k = \frac{2.303}{t} l o g \frac{100}{1}$

$t = \frac{4 .606}{k}$
