Integrated Rate Laws - Zero, First, & Second Order Reactions

WebPseudo-First order. A very important case is that of pseudo-first order kinetics. This is when a reaction is 2nd order overall but is first order with respect to two reactants. This is a very common kinetic scheme. r a t e = k [ A] [ B] where A and B are some generic reactants. Now the kinetics of this reaction can be a bit complicated. WebWhat are the orders with respect to each reactant, and what is the overall order of the reaction? Answer: order in NO = 2; order in H 2 = 1; overall order = 3 Check Your Learning In a transesterification reaction, a triglyceride reacts … 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. sqlbuilder where
