Question

ation. 7. Consider a collision-induced unimolecular decomposition reaction of the form A B+C. (a) Write down the three elementary steps in a Lindemann-Hinshelwood mechanism per- taining to such a decomposition reaction. (b) Use the steady-state approximation to obtain an expression for the rate of pro- duction of the products B and C, when the concentration of A is sufficiently high that (c) Express the rate you obtained in (b) in terms of the equilibrium constant pertain- ing to the activation process A A. (d) Obtain an expression for the latter equi- librium constant in terms of the energies EA and 8A, and effective degeneracies gA and ga, of A and A", respectively. (e) What do your results imply regarding the relation between the constants k2, gA gA EA, and εΑ., and the experimental pre- exponential factor and activation energy of the reaction (in the high concentration limit)? What additional assumption have you made in reaching your conclusion?
