WebWe can, but only for a first order reaction. Each 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. WebWe can see that the half-life of a first-order reaction is inversely proportional to the rate constant k. A fast reaction (shorter half-life) will have a larger k; a slow reaction (longer …
