In the coming section, let us understand the different types of reaction, and how to derive its half-life reaction. Half-life varies between different types of reactions. Same way, time can be determined with the knowledge of concentration and rate constant.
In pharmacokinetics, this principle of a half-life has a key role in the drug administration tests into the target, especially in the phase of elimination, where half-life is used in the calculation of time as to how fast a drug volume decrease in the given target after the reactant has been absorbed. Half-life principle is widely used in pharma to predict the concentration of a reactant over time. Half-life finds its applications in many fields of study such as pharmacokinetics, particle physics, carbon dating, etc.
