WebSep 2, 2015 · 1 For a certain first-order gas-hase reaction A → B + C the time required for half of an initial amount of A to decompose is 8.8 min. If the initial pressure of A is 400 mmHg, the time required to reduce the partial pressure of A to 50 mmHg is: (a) 1.1 min (b) 17.6 min (c) 26.4 min (d) 35.2 min (e) 70.4 min The correct answer is (c).
When radionuclides are used pharmacologically, for example in radiation therapy, they are eliminated through a combination of radioactive decay and biological excretion. An effective half-life of the drug will involve a decay constant that represents the sum of the biological and physical decay constants, as in the formula: With the decay constant it is possible to calculate the effective half-life using the formula: Webeffective half-life: the time required for the body burden of an administered quantity of radioactivity to decrease by half through a combination of radioactive decay and biologic …
WebJun 21, 2024 · Solution. If we compare the time that has passed to the isotope’s half-life, we note that 44.0 s is exactly 4 half-lives, so we can use Equation 13.1.1 with n = 4. Substituting and solving results in the following: a m o u n t r e m a i …
WebBased on the last equation, half life is the value of t for which N=N0/2. If we replace this in equation 3, we obtain: N02=N0e-t1/2. (4) Solving this equation for t1/2 yields: t1/2=ln (2) (5) This means we can determine an element’s half life by measuring its decay constant from experimental data. trustrainwear pttWebSep 8, 2024 · The physical half-life of F-18 is 1.83 hours and its biological half-life is approximately 6 hours, making its effective half-life approximately 1.4 hours (7). ...
