WebA pseudo second order reaction is a reaction for which the kinetics appear to be second order even though they are something else. Consider a third order reaction with the … 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.
