The rate constant for a first-order reaction is 0.54 s-1. What is the half-life of this reaction if the initial concentration is

Diano4ka-milaya [45]

Answer:

The half life time of first order reaction is 1.3 sec

Explanation:

Given:

First order rate constant $K = 0.54$ $M^{-1} s^{-1}$

Initial concentration $= 0.54$ M

From the formula of first order half life time,

$K = \frac{0.693}{t_{\frac{1}{2} } }$

So half life time is given by,

${t_{\frac{1}{y2} } } = \frac{0.693}{0.54}$

${t_{\frac{1}{y2} } } = 1.3$ sec

Therefore, the half life time of first order reaction is 1.3 sec.
