WebJan 30, 2024 · The half-life of a first-order reaction is a constant that is related to the rate constant for the reaction: t 1/2 = 0.693/ k. Radioactive … WebSep 12, 2024 · N = N0 2n. If the decay constant (λ) is large, the half-life is small, and vice versa. To determine the relationship between these quantities, note that when t = T1 / 2, then N = N0 / 2. Thus, Equation 10.4.4 can be rewritten as. N0 2 = N0e − λT1 / 2. Dividing both sides by N0 and taking the natural logarithm yields.

"WebThe rate of nuclear decay is also measured in terms of half-lives. The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days. In 14 more days, half of that remaining half will decay, and so on.
