Order in kinetic reaction

A second-order reaction (where order = 2) has a rate proportional to the concentration of the square of a single reactant or the product of the concentration of two reactants. The formula is: rate = k[A]2 (or substitute B for A or k multiplied by the concentration of A times the concentration of B), with the units of … See more Zero-order reactions (where order = 0) have a constant rate. The rate of a zero-order reaction is constant and independent of the concentration of reactants. This rate is independent of the concentration of the … See more A first-order reaction (where order = 1) has a rate proportional to the concentration of one of the reactants. The rate of a first-order reaction is … See more Chemical kinetics predicts that the rate of a chemical reaction will be increased by factors that increase the kinetic energy of the reactants (up to a … See more 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.
