WebWe can identify a 0, 1 st, or 2 nd order reaction from a plot of [A] versus t by the variation in the time it takes the concentration of a reactant to change by half. For a zero order reaction (Half life decreases with decreasing concentration.) For a … 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. epson ff-680 software download https://bablito.com

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
