WebJan 19, 2024 · First-order reactions are only dependent on the concentration of one reactant raised to the power of one. In other words, in first-order reactions, the rate is … 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.
