Chemistry zero order

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 WebASK AN EXPERT. Science Chemistry A zero-order reaction has a constant rate of 4.50x10-4 M/s. If after 45.0 seconds the concentration has dropped to 1.50x10-2 M, what was the initial concentration? Express your answer with the appropriate units. A zero-order reaction has a constant rate of 4.50x10-4 M/s.

12.4 Integrated Rate Laws - Chemistry 2e OpenStax

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 …
