WebJan 15, 2024 · The method of half-lives involved measuring the half-life’s dependence on concentration. The expected behavior can be predicted using the integrated rate laws we derived earlier. Using the definition of the half-life, at time t 1 / 2 the concentration [ A] drops to half of its original value, [ A] 0. [ A] = 1 2 [ A] o. at t = t 1 / 2. WebJul 20, 2013 · Amount remaining = Original Amount × ( 1 2) number of half lives. solve for X in the equation. 10 = X × ( 1 2) 1000 1590. Share.
