Question

The half life period of first reaction is 0.5 min at certain temperature calculate (a) rate constant of reactions
(b) the time required for 80

Answer 1

Explanation:

In first order reaction ,

$t \frac{1}{2} = \frac{0.693}{k} \\ = > k \: = \frac{0.693}{0.5} \\ = > k \: \: = 1.386 {min}^{ - 1}$
