WebThe systemic plasma clearance of i.v. prednisolone was dose-dependent and increased from 111 to 194 ml/min/1.73 m 2 over the 5 to 40 mg i.v. dosage range. The steady-state volume of distribution also increased, but little change … 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. WebKinetics: 6.34 - Half life. Definition of half-life.
