Order in kinetic reaction

WebKinetic parameters of the two individual reaction steps were characterized through isoconversional and combined kinetic analysis methods. It was found that the activation … WebMar 16, 2024 · The main principle of pseudo-zero-order kinetics is that the drug concentration is kept constant throughout course of reaction. Therefore, degradation rate does not depend on the concentration of the drug at saturation. Pseudo-zero-order reactions are mainly seen in solid dosage forms and suspensions.
