Web9 sept. 2016 · Thus we have solve the following differential equation: dN dt = 100 − λN(t) We can rearrange: dN 100 − λN(t) = dt ∫ dN 100 − λN(t) = ∫dt − 1 λ ln(100 − λN(t)) = t + C − 1 λ ln(100 − λN(t)) = t + C which, after solving for the constant, gives us: N(t) = 100 − 100e − λt λ Web16 nov. 2024 · Half life equation. Every decaying substance has its own half life, because half life is the amount of time required for exactly half of our original substance to decay, leaving exactly half of what we started with. Because every substance decays at a different rate, each substance will have a different half life. But regardless of the ...
WebFor a first-order reaction, the half-life is given by: t1/2 = 0.693/k For a second-order reaction, the formula for the half-life of the reaction is: 1/k [R]0 Where, t 1/2 is the half-life of the reaction (unit: seconds) [R 0] is the initial reactant concentration (unit: mol.L -1 or M) Web23 iun. 2024 · Equation 1: ln [ Ao ]/ [ A ]=kt Equation 2: t-half= 0.693/k Equation 3: t-half= 0.693*Vd/CL, where Vd is the volume of distribution and CL is clearance It is also worth discussing the relationship between the percentage …
