Determining the half life and rate constant for a first order

WebTo calculate the half-life, we want to know when the quantity reaches half its original size. Therefore, we have y 0 2 = y 0 e − k t 1 2 = e − k t − ln 2 = − k t t = ln 2 k . y 0 2 = y 0 e − … WebSep 23, 2013 · Here is an easy way to do half life calculations without using logs or exponents. The example problem works well since the starting and end masses are multip... WebAug 8, 2024 · Thus, a cobalt-60 source that is used for cancer treatment must be replaced regularly to continue to be effective. Figure 11.5.1: For cobalt-60, which has a half-life of 5.27 years, 50% remains after 5.27 years (one half-life), 25% remains after 10.54 years (two half-lives), 12.5% remains after 15.81 years (three half-lives), and so on. picto four
