Half Life Formula and Doubling Time Formula - Math Help

WebTo begin, we’ll count the number of half-lives that have passed. This can be obtained by doing the following: Half-life (t½) = 2.4 mins Time (t) = 7.2 mins Number of half-lives Number of half-lives n = t t 1 / 2 n = 7.2/2.4 = 3 Thus, three half-lives have passed. Finally, we will calculate the remaining amount. WebEach order has its own half-life equation. Zeroth order: ( [A0]/2k) First order: (ln (2)/k) Second order: (1/k [A0]) So the zeroth and second order require us to know the rate constant and the initial concentration, while the first order only requires the rate constant. Hope that helps. ( 1 vote) Data a year ago paliperidone level

WebI can do this by working from the definition of "half-life": in the given amount of time (in this case, 9.45 minutes), half of the initial amount will be gone. That is, from t = 0 to t = 9.45 , I will have gone from 100% (" 1 ") of however much I started with to 50% of that amount (converted to 0.5 for use inside the formula).
