scribing this reaction scheme are cast in a nondimensional form and analyzed in four basic approximation regimes: a 'pseudo-first order' approximation valid for small values of the ratio of the initial concentrations of the reactants; an asymptotic solution valid for large values of k S ; the standard steady state (Bodenstein) approximation; and an approximation to a second order system without intermediate. Interconnecting relationships between the various approximations derived are examined, and the approximations are compared to numerical solutions to the full equations. The results are assessed from the standpoint of the experimental kineticist, and it is suggested that the reaction studied. and consequently many other more complex reactions, may under certain circumstances be subject to non-unique interpretation.
We examine the kinetic model A + B
