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 ... 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.
WebFeb 2, 2024 · In a zeroth-order reaction, the rate constant must have the same units as the reaction rate, typically moles per liter per second. Although it may seem counterintuitive for the reaction rate to be independent of the reactant concentration (s), such reactions are rather common. WebFeb 19, 2024 · Let x/xo be percentage decrease in concentration of the reactants. For a zero order reaction, ∆x/xo = -kt For ∆x/x = -20%, -20% = -k × 10 k = 20/100 × 10 k = 2 Now …
