Half life equation kinetics
WebThe rate for radioactive decay is: decay rate = λN with λ = the decay constant for the particular radioisotope. The decay constant, λ, which is the same as a rate constant discussed in the kinetics chapter. It is possible to express the decay constant in terms of the half-life, t1/2: λ = ln 2 t 1 / 2 = 0.693 t 1 / 2 or t 1 / 2 = ln 2 λ = 0 ...
