Half life of ...

Question

Half life of radioactive element $_{92}^{238} U$ is independent of the initial amount of radioactive element taken. What will be the decay order of the element?

Open in App

Solution

Decay order is first. As $t 1 / 2$ is independent of initial amt.
$t 1 / 2 α \frac{1}{K}$
$t 1 / 2 = \frac{0.693}{K}$
