Web8 years ago. In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant).

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.

WebYes, zero-order reactions have a half-life equation as well. 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. incompatibility\\u0027s zvWebFeb 12, 2024 · Zero-order kinetics is always an artifact of the conditions under which the reaction is carried out.
