WebZero-order Reactions Definition. A zero-order reaction is a reaction that's rate is independent of the concentration of the reactant (s). The rate is only dependent on the rate constant (k). The rate equation for this type of reaction is rate = k. Now, zero-order reactions aren't entirely independent of concentration. WebThe 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. [A]0/2 = -kt + [A]0, after the substitution. - [A]0/2 = -kt, subtract [A]0 from both sides of the equation. [A]0/2 = kt, divide by -1 on both sides. [A]0/2k = t, divide by k on both sides.
