Chemistry zero order
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 … WebFor zero-order reactions, the differential rate law is: rate = k A zero-order reaction thus exhibits a constant reaction rate, regardless of the concentration of its reactant (s). This may seem counterintuitive, since the reaction rate certainly can’t be finite when the reactant concentration is zero.

WebSep 19, 2024 · The reaction is zero order in CO; thus n = 0. The rate law is: \[\ce{rate}=k[\ce{NO2}]^2[\ce{CO}]^0=k[\ce{NO2}]^2 \nonumber \] Remember that a number raised to the zero power is equal to 1, thus [CO] 0 = 1, which is why we can simply drop the concentration of CO from the rate equation: the rate of reaction is solely dependent on …
