Rate law and reaction order (video) Khan Academy

Web8 years ago. In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant). WebJan 30, 2024 · The integrated rate law for the first-order reaction A → products is ln [A]_t = -kt + ln [A]_0. Because this equation has the form y = mx + b, a plot of the natural log of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k. Created by Jay. Sort by: WebMar 18, 2024 · First-order kinetics is also referred to as non-saturable or linear kinetics.

WebFeb 2, 2024 · Because the reaction is first order both in A and in B, it has an overall reaction order of 2. (The integrated rate law for this reaction is rather complex, so we will not describe it.) We can recognize second-order reactions of this sort because the reaction rate is proportional to the concentrations of each reactant. WebFeb 28, 2024 · In a first order reaction, there will be one reactant present in the rate law. For a second order reaction, you can either have a rate law with one reactant to the … phenylephrine mapWebThe order of reaction determines the relationship between the rate of reaction and the concentration of reactants or products. It is the power to which a concentration is raised in the rate law equation. For example, for the reaction xA + yB ---> products, the rate law equation will be as follows: Rate = k [A]^a .
