Abstract : This is the third of a series of reports, in each of which a hypothetical reaction system with an idealized type of chemical kinetics is carefully scrutinized. The analytical solutions for the system A k1 B k2k3 C are explored for characteristic features which are useful to the kineticist in determining the rate constants from fragmentary experimental data. It is found that B exhibits a maximum whenever k sub 3 < k sub 1. This maximum and the time at which it occurs are among the most useful features in determining the rate constants. A critical examination of the pseudostationary state approximation for B as applied to this system is made, and a related approximation to C is introduced. The approximations are found to have a similar range of validity. The time at which C is at an arbitrary percent of its equilibrium concentration is studied. Under certain conditions this time is essentially independent of one or more of the rate constants. (Author)
