Can rate law be negative
WebThe rate law is experimentally determined to be: rate = k [NO 2] 2. Therefore, we would say that the overall reaction order for this reaction is second-order (the sum of all exponents in the rate law is 2), but zero-order for [CO] and second-order for [NO 2 ]. The reaction order is most often a whole number such as 0, 1, or 2; however, there ... WebFeb 12, 2024 · The following orders are possible: Zero: A zero order indicates that the concentration of that species does not affect the rate of a reaction. Negative integer: A negative order indicates that the concentration of that species INVERSELY affects the …

WebNegative order. A reaction rate can have a negative partial order with respect to a substance. For example, the conversion of ozone (O 3) to oxygen follows the rate … WebThus, the order can be negative only for the complex reaction, with respect to a substance, with undefined overall order. In such case, the negative partial order indicates that that...
WebMar 13, 2016 · The answer says no, the rate constant can never be negative because the Rate can never be negative, since Rate=k [R] n. I don't feel completely comfortable with this answer/reasoning, mostly because the rate law for reactants do seem to have a negative rate, where the concentration decreases over time. WebJul 16, 2008 · You'd be correct though, that a negative order would mean that increasing one of the reactants would decrease the rate of the reaction. In an industrial …
WebA reaction rate can have a negative partial order with respect to a substance. For example, the conversion of ozone (O 3) to oxygen follows the rate equation in an excess of oxygen. This corresponds to second order in ozone and order (−1) with respect to oxygen. [29]
