WebThe rate of a second-order reaction may be proportional to one concentration squared, or (more commonly) to the product of two concentrations, As an example of the first type, the reaction NO2 + CO → NO + CO2 is second-order in the reactant NO2 and zero order in the reactant CO. 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 13, 2016 · Zero, First, and Second Order Reactions refer to the dependence of the reaction's rate on the initial concentration of reactant (s). For a zero order, the rate of reaction does not depend at all on the reactant's concentration. For first order, it is directly dependent on concentration (for example doubling the concentration will double the rate). WebJan 8, 2024 · A zeroth-order reaction is one whose rate is independent of concentration; its differential rate law is rate = k.
