Deriving half life equation

WebBecause radioactive decay is a first-order process, radioactive isotopes have constant half-lives. Half-life is symbolized by t1/2, and it's the time required for 1/2 of a sample of a particular radioactive isotope to decay. For example, the half-life of Strontium-90 is equal to 28.8 years.

Web8 years ago. In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant).
