We can derive it the same way we derive the half-life equations for the first and second-order reactions. The given integrated rate law of a zero-order reaction is: [A]t = -kt + [A]0. At half-life the concentration is half of its original amount, so [A]t = [A]0/2. fitness band wrap

"WebA zero-order reaction thus exhibits a constant reaction rate, regardless of the concentration of its reactant (s). This may seem counterintuitive, since the reaction rate certainly can’t be finite when the reactant concentration is zero. " - In a zero order reaction 20%

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.
