WebJan 3, 2024 · Zero order kinetics is a way of describing how the body uses and breaks down some medicines. While the rate at which the body eliminates most drugs is proportional to the concentration... WebSep 27, 2024 · 1. As far as I understand, the assumption that the RDS has a zero-order is false. The RDS has its order equal to its respective molecularity, however, in zero-order reactions, the rate-determining step will not have the initial reactants as parts of the elementary step. Thus, when you calculate the rate constant in terms of the initial ...
WebA zero order reaction is independent of the concentration of the reactants. One example could be an enzyme-catalysed reaction, where the enzyme is not (by definition) a reactant, but nevertheless the concentration of enzyme is what determines the reaction rate, not the concentration of reactant. This would be a zero order reaction. 2 comments Web“A zero-order reaction is a chemical reaction in which the rate remains constant as the concentration of the reactants rises or falls.” The rate of these reactions is always equal to the rate constant of the specific …
WebThe meaning of ZERO-ORDER REACTION is a chemical reaction in which the rate of reaction is constant and independent of the concentration of the reacting substances. WebThe reaction is zero order in CO; thus n = 0. The rate law is: rate = k[NO2]2[CO]0 = k[NO2]2 Remember that a number raised to the zero power is equal to 1, thus [CO] 0 = 1, which is why the CO concentration term may be omitted from the rate law: the rate of reaction is solely dependent on the concentration of NO 2.
WebJul 4, 2024 · A zero-order reaction is typically denoted graphically by an asymptote, which indicates the rate limit of the reaction. When an enzyme-substrate reaction tends toward zero order, the only way to make a reaction speed up is to add more enzyme, therefore adding more active sites.
