How to determine rate order
WebFeb 12, 2024 · In order to determine the reaction order with respect to A, one must note in which experiment A is changing; that is, between experiments 1 and 2. Write a rate law … WebThat's what we saw up here, the slope is equal to the rate constant. And the Y intercept, so this point right here, this should be one over the initial concentration of A. So this point right here is one over the initial concentration of A. So that's the idea of the integrated rate law, or the integrated rate equation for a second order reaction.

WebJan 2, 2024 · The units of the rate constant depend on the order of reaction. In general, for a reaction with order a + b, the units of the rate constant are mol 1− (m+n) ·L (m+n)−1 ·s −1 For a zero order reaction, the rate constant has units molar per second (M/s) or mole per liter per second (mol·L −1 ·s −1) WebScience Chemistry N2O5 (g), decays according to the first order. Calculate the initial rate of decay of nitrous oxide under conditions where 3.45 g of N2O5 is placed in a flask of volume of 0.750 L and heated to 65 °C. The rate constant for this reaction is k = 5.2 x 10 -3 s -1. N2O5 (g), decays according to the first order.
WebOne method of using graphs to determine reaction order is to use relative rate information. Plotting the log of the relative rate versus log of relative concentration provides information about the reaction. Here is an example of data from a zeroth-order reaction: Varying [A] does not alter the reaction rate.
