The Richard Stockton College of New Jersey Chemistry Program, School of Natural Sciences and Mathematics PO Box 195, Pomoma, NJ CHEM 3410: Physical Chemistry I | Fall 2008 More kinetics practice problems December 1, 2008 1. For the following recombination reaction: 3 A(g) +M(g)!A3(g) +M(g) the empirical rate law is believed to have the form: d[A3] dt = k[M] [A2] [A] where , , and are the orders with respect to A, A2 and A, which are to be determined by initial rate data. [NOTE that A2 is not a typo. The species A2 is found empirically to be involved in the reaction mechanism.] (a) The rate of the reaction can be monitored by observing either d[A]dt or d[A3]dt . What is the relationship between d[A]dt and d[A3]dt imposed by the reaction stoichiometry? (b) The observed initial rates obtained from measurements of [A] at some early time and the initial amount of A are (concentrations in molarity, M): Table 1: default [A] [A2] [M] rate 0.01 0.01 1.00 1.0 0.02 0.01 1.00 4.0 0.02 0.02 1.0...
