WebFeb 25, 2015 · You could plot the data to determine the order of the reaction. I would use Microsoft Excel to do this. Reproduce the data and then add columns that calculate the ln [ A] and 1 [ A]. Then plot [ A], ln [ A] ,and 1 [ A] vs. time (I would use separate plots). 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.

WebMar 5, 2024 · For the reaction, A + B → products, the rate law is rate = k[A]m[B]n where m and n are the orders of reaction with respect to A and B. If one reactant, say B is present in large excess, its concentration is essentially constant during the course of the reaction. The rate law becomes rate = k[B]n[A]m = kobs[A]m where kobs = k[B]n WebApr 12, 2024 · 773 views, 14 likes, 2 loves, 20 comments, 2 shares, Facebook Watch Videos from JoyNews: UPFront with Raymond Acquah is live on the JoyNews channel. iowa state university greek
