Half-Life (t½) Calculation

Introduction to Half-Life (t½) Calculation

The half-life of a substance is the time taken for half of the original substance to decay. The half-life equation is a fundamental concept in pharmacology, chemistry, and radioactive decay. The formula for calculating half-life is t½ = (ln(2) / k), where t½ is the half-life, ln(2) is the natural logarithm of 2, and k is the decay constant.

Parameter usage:

• initialAmount= initial amount of the substance
• decayConstant= decay constant of the substance

Output:

• t½= the half-life of the substance

Data validation

The initial amount should be greater than zero, and the decay constant should be a positive non-zero value.

Summary

This calculator allows for the determination of the half-life of a substance based on its initial amount and decay constant. It is a valuable tool in pharmacology and chemical kinetics.
