Elimination Rate Constant Calculator

Formula

To calculate the elimination rate constant ( $k$ ):

$k = \frac{0.693}{t_{1/2}}$

Where:

$k$ is the elimination rate constant
$t_{1/2}$ is the half-life time

What is the Elimination Rate Constant?

The elimination rate constant ( $k$ ) is a measure of the rate at which a substance is removed from the body. It is calculated by dividing 0.693 by the half-life time ( $t_{1/2}$ ).

Example Calculation 1

Let's assume the following value:

Half-Life Time ( $t_{1/2}$ ) = 5 hours

Using the formula:

$k = \frac{0.693}{5} = 0.1386 \text{ per hour}$

The elimination rate constant is 0.1386 per hour.

Example Calculation 2

Let's assume the following value:

Half-Life Time ( $t_{1/2}$ ) = 10 hours

Using the formula:

$k = \frac{0.693}{10} = 0.0693 \text{ per hour}$

The elimination rate constant is 0.0693 per hour.
