WebThe most intuitive mathematical description of decay rate is half-life, which can be calculated by our radioactive decay calculator. The Half life equation for the relation between the half-life, decay constant, and mean lifetime is: $$ t_ {1/2} = ln (2) / λ = τ ln (2) $$. where, t1 / 2 = half-life of the particle. τ = half-life. WebHere t = t1/2 ( half life) and as per the definition Half life is time at which the concentration of "A" is half of the initial concentration , so, [A]t = [A]o/2 . Thus, here, he assigned 1/ [A]t as 1/ [A]o/2, which can also be written as 2/ [A]o. Hope this helps you. ( 4 votes) Alecia M. Fordham 6 years ago what is a half life? • ( 2 votes)
