WebOct 3, 2024 · The definition of a “half-life” is the time that it takes for 1 2 of the compound to decay. SO, we just need to find the point (number of years) at which a 5.471% decrease … WebThe half-life formula is derived using 1st order kinetics since radioactive decay is a first order reaction. A first order reaction has the general form of: A -> products. For … 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.
