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.
