Question

A reaction has a half-life of 10 minutes. Calculate the rate constant for the first order reaction.

Open in App

Solution

The half life period is 10 minutes.
$t_{1 / 2} = 10$ minutes.
The rate constant for the first order reaction $k = \frac{0.693}{t_{1 / 2}} = \frac{0.693}{10 m i n} = 0.0693 / m i n$
